A reaction mechanism has the following proposed elementary steps: Step 1: A ⇌ B + C Step 2: A + B → D Step 3: 2 A + D → C + E

Which of the following equations would represent the overall reaction for this mechanism?

Which species are intermediates in this reaction?

Which of the following would be the correct elementary rate law for Step 1?

Which of the following would be the correct elementary rate law for Step 2?

Which of the following would be the correct elementary rate law for Step 3?

If Step 1 is the rate-limiting step, what would the proposed rate law for this mechanism be?

Expert Solution
Step 1

The given steps of the reaction are:

Step 1: AB+CStep 2: A+BDStep 3: 2A+DC+E

In chemical kinetics, the slowest step of the reaction is the rate-determining step and the order of the reaction depends upon it.
