AP Kinetics Test Review

Front

What does the collision theory state?

Back

Atoms, ions, or molecules must collide in order to react.

Front

How can the reaction rate for the reaction between copper and silver nitrate be measured?

Back

Change in color (colorimetry).

Front

What happens to the fraction of molecules with energy > E_a at higher temperatures?

Back

It increases.

Front

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

Back

It is not dependent upon the original concentration.

Front

What is FALSE about the Maxwell Boltzmann distribution curve?

Back

At higher temp, area under curve is greater than at low temp.

Front

Define activation energy (E_a).

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the rate law?

Back

An equation that relates the rate of a reaction to the concentration of its reactants.

Front

What is the significance of the area under the Maxwell Boltzmann curve?

Back

It represents the number of particles with a given energy.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates.

Front

What is a first order reaction?

Back

A reaction whose rate is directly proportional to the concentration of one reactant.
