Question

1.)

What is the rate law for the following mechanism in terms of the overall rate constant kkk?

A-

Step1:Step2:A+BB+C⇌→CD(fast)(slow)Step1:A+B⇌C(fast)Step2:B+C→D(slow)

Express your answer in terms of kkk and the necessary concentrations (e.g., k*[A]^3*[D]).

B-

Consider the reaction

2X2Y2+Z2⇌2X2Y2Z2X2Y2+Z2⇌2X2Y2Z

which has a rate law of

rate=rate= k[X2Y2][Z2]k[X2Y2][Z2]

Select a possible mechanism for the reaction.
