Calculating the Rate Laws of Multi-step Reactions (14.4.3)

Question 1

• If a proposed reaction mechanism is consistent with the experimentally determined rate law, the proposed mechanism might be correct; if a proposed
mechanism is not consistent with the experimentally-determined rate law, the proposed mechanism is incorrect.

Answer 1

• If a proposed reaction mechanism is consistent with the experimentally determined rate law, the proposed mechanism might be correct; if a proposed mechanism is not consistent with the experimentally-determined rate law, the proposed mechanism is incorrect.

Question 2

• If the first elementary step of the reaction mechanism is not the rate-determining step, the derived rate law will often include reaction intermediates.

Answer 2

• If the first elementary step of the reaction mechanism is not the rate-determining step, the derived rate law will often include reaction intermediates.

Question 3

• The rate law must be written in terms of known concentrations.

Answer 3

• The rate law must be written in terms of known concentrations.

Question 4

• If an elementary step is fast, the reverse of the elementary step will also be fast.

Answer 4

• If an elementary step is fast, the reverse of the elementary step will also be fast.
