Questions and Answers

What is the relationship between the orders of reaction of individual reactants and the overall reaction order?

The overall reaction order is the average of the individual orders.

The overall reaction order is calculated by adding the individual orders. (correct)

They are equal to each other.

The overall reaction order is the highest of the individual orders.

What is the primary purpose of differential rate laws?

To predict the reaction rate at a specific temperature.

To determine the rate constant of a reaction.

To describe the overall mechanism of a reaction. (correct)

To calculate the concentration of reactants at equilibrium.

What is the primary difference between differential and integrated rate laws?

Differential rate laws express the reaction rate as a function of time, while integrated rate laws express the reaction rate as a function of concentration.

Differential rate laws describe the reaction rate, while integrated rate laws describe the reaction mechanism.

Differential rate laws describe the reaction mechanism, while integrated rate laws describe the reaction rate.

Differential rate laws express the reaction rate as a function of concentration, while integrated rate laws express the reaction rate as a function of time. (correct)
