Determining the Rate Laws of Elementary Reactions (14.4.2)

Question 1

• If a reaction aA + bB ! cC + dD is an elementary step, the stoichiometric coefficients a and b are the values of the orders m and n in the rate law.

Answer 1

• If a reaction aA + bB ! cC + dD is an elementary step, the stoichiometric coefficients a and b are the values of the orders m and n in the rate law.

Question 2

• The reaction rate of the overall reaction is determined by the rate of the slowest elementary step, called the rate-determining step.

Answer 2

• The reaction rate of the overall reaction is determined by the rate of the slowest elementary step, called the rate-determining step.

Question 3

• If a proposed reaction mechanism is consistent with the experimentally determined rate law, the proposed mechanism is possible; if a proposed mechanism is inconsistent with the rate law, the mechanism is definitely incorrect.

Answer 3

• If a proposed reaction mechanism is consistent with the experimentally determined rate law, the proposed mechanism is possible; if a proposed mechanism is inconsistent with the rate law, the mechanism is definitely incorrect.
