AP Chem Kinetics Review

Front

What is the definition of reaction kinetics?

Back

Reaction kinetics is the study of the rates of chemical reactions and the factors that affect these rates.

Front

What is the overall order of a rate law?

Back

The overall order of a rate law is the sum of the exponents of the concentration terms in the rate equation.

Front

In the rate law Rate = k[A]^2[B]^1, what is the overall order?

Back

The overall order is 3rd order (2 from [A] and 1 from [B]).

Front

What does it mean if a reaction is described as exothermic?

Back

An exothermic reaction is one that releases energy, usually in the form of heat, to the surroundings.

Front

How do you determine the rate of a reaction from the rate of product formation?

Back

The rate of a reaction can be determined from the rate of product formation by using stoichiometry; for example, if 2 moles of A produce 2 moles of C, the rate of reaction is half the rate of C formation.

Front

What is the significance of the slowest reaction in a series of reactions?

Back

The slowest reaction in a series of reactions is the rate-determining step, which controls the overall rate of the reaction.

Front

What is the unit of rate in chemical kinetics?

Back

The unit of rate in chemical kinetics is typically expressed in mol/L*s (molarity per second).

Front

What is the relationship between concentration and reaction rate?

Back

Generally, an increase in the concentration of reactants leads to an increase in the reaction rate, as there are more particles available to collide.

Front

What is the effect of temperature on reaction rates?

Back

Increasing the temperature typically increases the reaction rate, as it provides more energy to the reactants, leading to more frequent and effective collisions.

Front

What is a rate law?

Back

A rate law is an equation that relates the rate of a reaction to the concentration of its reactants, typically in the form Rate = k[A]^m[B]^n.
