The reaction is completed in a shorter amount of time<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>A catalyst is a substance that speeds up a chemical reaction without being consumed in the process. It achieves this by providing an alternative reaction pathway with a lower activation energy. Activation energy is the minimum energy required for a reaction to occur. By lowering this barrier, a catalyst increases the rate at which the reaction reaches equilibrium.<\/p>\n\n\n\n<p>Here\u2019s how each option relates to the function of a catalyst:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. A more desirable product is often formed<\/strong>: This is not necessarily true. A catalyst does not alter the products of a reaction; it only affects the rate at which equilibrium is reached. The products and their distribution remain the same as they would without the catalyst.<\/li>\n\n\n\n<li><strong>B. The reaction is completed in a shorter amount of time<\/strong>: This is correct. By lowering the activation energy, a catalyst allows the reaction to proceed more quickly, so the reaction reaches completion faster.<\/li>\n\n\n\n<li><strong>C. The yield of product is increased<\/strong>: The yield, or the amount of product formed, is not affected by a catalyst. A catalyst does not change the equilibrium position of the reaction; it simply helps achieve equilibrium more quickly.<\/li>\n\n\n\n<li><strong>D. A greater amount of energy is released by the reaction<\/strong>: A catalyst does not change the energy released by the reaction. It affects the rate of the reaction, not the energy involved. The total energy change between reactants and products remains the same, regardless of whether a catalyst is present.<\/li>\n<\/ul>\n\n\n\n<p>In summary, catalysts are crucial for increasing reaction rates by providing a more efficient pathway for the reaction, but they do not alter the overall yield or energy of the reaction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following best describes the result of using a catalyst in a chemical reaction?
