AP Chemistry Review Questions (part 2)

Front

If [A] vs time is linear, the reaction is _____

Back

Zero order reactions have a constant rate that does not depend on the concentration of the reactant.

Front

In the equation PV=nRT, the units for T are

Back

Kelvin is the SI unit for temperature used in gas law equations.

Front

Which reaction step is slower?

Back

The slowest step in a reaction mechanism is known as the rate-determining step.

Front

Breaking bonds is

Back

Endothermic processes require energy input to break chemical bonds.

Front

When a salt dissolves in water, which IMF forms?

Back

Ion-dipole interactions occur between the ions of the salt and the polar water molecules.

Front

What is the rate law for a zero-order reaction?

Back

Rate = k, where k is the rate constant.

Front

What is the relationship between temperature and reaction rate?

Back

Generally, an increase in temperature increases the reaction rate.

Front

What is the significance of the activation energy in a chemical reaction?

Back

Activation energy is the minimum energy required for a reaction to occur.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a reaction without being consumed.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release heat, while endothermic reactions absorb heat.
