The equation for Gibbs free energy is: \u0394G=\u0394H\u2212T\u0394S\\Delta G = \\Delta H &#8211; T\\Delta S<\/p>\n\n\n\n<p>where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\u0394H\\Delta H is the change in enthalpy (heat energy).<\/li>\n\n\n\n<li>TT is the absolute temperature.<\/li>\n\n\n\n<li>\u0394S\\Delta S is the change in entropy (disorder).<\/li>\n<\/ul>\n\n\n\n<p>For a solution to form spontaneously, the overall change in Gibbs free energy must be negative (\u0394G&lt;0\\Delta G &lt; 0).<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>An increase in the disorder of a system<\/strong>: This favors spontaneity. When a solution forms, the mixing of solute and solvent typically increases the disorder (or entropy, \u0394S\\Delta S). A positive \u0394S\\Delta S contributes to making \u0394G\\Delta G negative, favoring spontaneity.<\/li>\n\n\n\n<li><strong>A decrease in the internal energy of a system<\/strong>: This also favors spontaneity. A decrease in internal energy (\u0394H\\Delta H) generally makes \u0394G\\Delta G more negative, especially if the temperature is high. For example, the process of dissolving a substance might release energy (exothermic process), which decreases the system&#8217;s internal energy and supports the spontaneous formation of a solution.<\/li>\n\n\n\n<li><strong>An increase in the internal energy of a system<\/strong>: This does not favor spontaneity. When the internal energy increases, the system tends to become less stable. If \u0394H\\Delta H is positive (endothermic process), it makes \u0394G\\Delta G less negative, reducing the likelihood of spontaneous solution formation.<\/li>\n\n\n\n<li><strong>A decrease in the disorder of a system<\/strong>: This also does not favor spontaneity. A decrease in disorder (negative \u0394S\\Delta S) would make \u0394G\\Delta G more positive, thus hindering the spontaneous formation of a solution.<\/li>\n<\/ol>\n\n\n\n<p>In summary, the formation of a solution is spontaneous if the system\u2019s entropy increases and its internal energy decreases, leading to a negative change in Gibbs free energy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following favor the spontaneous formation of a solution?Select all that apply:An increase in the disorder of a systemAn increase in the internal energy of a systemA decrease in the internal energy of a systemA decrease in the disorder of a system The correct answer and explanation is: The correct answers are: Explanation: [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[25],"tags":[],"class_list":["post-275158","post","type-post","status-publish","format-standard","hentry","category-exams-certification"],"_links":{"self":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/275158","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/comments?post=275158"}],"version-history":[{"count":0,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/posts\/275158\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/media?parent=275158"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/categories?post=275158"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.learnexams.com\/blog\/wp-json\/wp\/v2\/tags?post=275158"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
