CHEM121 GENERAL CHEMISTRY LAB Module 4 Final Assessment Q & A 2026 (Complete And Verified Study material) (17pages) LEARNEXAMS

(Some Questions denote their format. All questions are answered) 1. True or False: The rate of a chemical reaction is only affected by the concentration of the reactants. - Answer: False. Rationale: The rate of a chemical reaction is influenced by several factors, including the concentration of reactants, temperature, presence of a catalyst, and surface area of solid reactants. 2. In the context of enzyme kinetics, what does the term 'Vmax' represent? _________. - Answer: Vmax represents the maximum rate of an enzymatic reaction when the enzyme is saturated with substrate. 3. Multiple Choice: Which of the following is not a type of reaction intermediate? A) Carbocation B) Carbanion C) Free radical D) Transition metal - Answer: D) Transition metal. Rationale: Transition metals are not considered reaction intermediates; they are often catalysts or part of the coordination complexes in reactions. 4. Fill in the blank: In a redox reaction, the substance that gains electrons is called the _________. - Answer: oxidizing agent. Rationale: The oxidizing agent gains electrons and is itself reduced in the process. 5. True or False: A reaction mechanism must always agree with the stoichiometry of the overall balanced equation. - Answer: True. Rationale: The reaction mechanism must account for the stoichiometry of the overall reaction, as it provides the step-by-step pathway by which reactants convert to products.
