Consider the following four energy diagrams:

(a) Which diagrams correspond with a two-step mechanism?

(b) Which diagrams correspond with a one-step mechanism?

(c) Compare energy diagrams A and C. Which has a relatively larger E_a?

(d) Compare diagrams A and C. Which has a negative ΔG?

(e) Compare diagrams A and D. Which has a positive ΔG?

(f ) Compare all four energy diagrams. Which one exhibits the largest E_a?

(g) Which processes will have a value of K_eq that is greater than 1?

(h) Which process will have a value of K_eq that is roughly equal to 1?
