AP Kinetics Review

Front

What happens to reactants in a forward chemical reaction?

Back

Typically, some of the reactants go forward toward the products.

Front

How can the oxidation rate of steel wool be increased?

Back

By increasing the amount of oxygen.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a reaction by providing a pathway that has a lower activation energy.

Front

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

Back

The time required for the concentration of a reactant to decrease to half its initial value.

Front

If the half-life for a first-order reaction is 32 s, what is the original concentration if the concentration after 2.0 minutes is 0.062 M?

Back

The original concentration is 0.84 M.

Front

What does the Maxwell-Boltzmann distribution illustrate?

Back

It illustrates the distribution of particle speeds in a gas.

Front

In a Maxwell-Boltzmann distribution, which curve represents the highest proportion of particles moving the fastest?

Back

The curve that peaks on the right, often represented in blue.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the reactants.

Front

What is the effect of concentration on reaction rates?

Back

Increasing the concentration of reactants typically increases the rate of reaction.
