1. For an irreversible reaction A products, the graph of 1/[A] as a function of time is linear. What is the reaction order in A? a. Zeroth-order b. First-order c. Second-order d. The order in A cannot be determined based on the information given. 2. A proposed mechanism for the reduction of nitrogen as NO by hydrogen is: Step 1: H₂ (g) + 2 NO (g) → N₂O (g) + H₂O (g) - Step 2: N₂O (g) + H₂ (g) → N2 (g) + H₂O (g) What is the molecularity of Step 2? a. unimolecular b. bimolecular c. termolecular d. zero molecular (spontaneous) e. More information is needed to answer this question. 3. Which one of the following will change the value of an equilibrium constant? a. changing temperature b. adding other substances that do not react with any of the species involved in the equilibrium c. varying the initial concentrations of reactants d. varying the initial concentrations of products e. changing the volume of the reaction vessel
