1) Predict the overall reaction from the following two-stepmechanism:

2A -> A2 (slow)

A2 + B -> A2B (fast)

Express your answer as a chemical equation.

2) Predict the rate law from the following two-stepmechanism:

2A -> A2 (slow)

A2 + B -> A2B (fast)

Express your answer in terms of k, [A]and [B] as necessary.

3) What is the rate law for the following mechanism in termsof the overall rate constant k?

Step 1: A + B ? C (fast)
Step 2: B + C -> D (slow)

Express your answer in termsof k and thenecessary concentrations(e.g., k*[A]^3*[D]).

4) Using the results of the Arrhenius analysis(Ea=93.1kJ/moland A=4.36×1011M?s?1), predict the rateconstant at 342 K .

Express the rate constant in liters per mole-second tothree significant figures.
