The mechanism of a chemical reaction is given below.   (CH3)3CCl → (CH3)3C+ + Cl– (slow)   (CH3)3C+ + OH– → (CH3)3COH (fast) Which of the following statements concerning the reaction is/are correct?   1. The overall balanced reaction is: (CH3)3CCl + OH– → (CH3)3COH + Cl–   2. Hydroxide ion is a reaction intermediate.   3. The following rate law is consistent with the mechanism: rate = k[(CH3)3CCl]OH–].

Below is a proposed mechanism for the decomposition of H2O2. H2O2 + I– → H2O + IO– slow H2O2 + IO– → H2O + O2 + I– fast Which of the following statements is incorrect?

For a certain reaction of the general form aA → products, a plot of the experimental data of ln[A] versus time is linear. What is the reaction order with respect to the reactant (A)?

For the equilibrium PCl5(g) PCl3(g) + Cl2(g), Kc = 4.0 at 228°C. If pure PCl5 is placed in a 1.00-L container and allowed to come to equilibrium, and the equilibrium concentration of PCl5(g) is 0.19 M, what is the equilibrium concentration of PCl3?
