AP Chemistry - Unit 5 - Thou Shall Not Forget

Front

What is the order of a reaction if the concentration of reactants affects the rate linearly?

Back

First order reactions have a linear relationship between concentration and rate.

Front

What is the half-life of a first order reaction?

Back

The half-life of a first order reaction is constant and does not depend on the initial concentration.

Front

What is the rate law for a reaction with the elementary step A + A → B + B?

Back

rate = k[A]^2

Front

True or False: The average kinetic energy of particles under a specific curve is proportional to temperature.

Back

True

Front

What is the unit for the rate constant (k) for second order reactions?

Back

M^-1 s^-1

Front

What does a zero order reaction imply about the concentration of reactants?

Back

In a zero order reaction, the rate is constant and does not depend on the concentration of reactants.

Front

How does the rate of a first order reaction change with increasing concentration?

Back

The rate increases linearly with increasing concentration in a first order reaction.

Front

What is the relationship between temperature and kinetic energy of particles?

Back

As temperature increases, the average kinetic energy of particles also increases.

Front

What is the integrated rate law for a first order reaction?

Back

ln[A] = -kt + ln[A]₀

Front

What is the significance of the rate constant (k) in a rate law?

Back

The rate constant (k) indicates the speed of the reaction and is specific to the reaction at a given temperature.
