AP Chemistry - Unit 5 - Thou Shall Not Forget

Front

What is the order of a reaction if quadrupling the concentration results in a quadrupling of the rate?

Back

First order

Front

What is the order of the half-life of Carbon-14?

Back

First order

Front

What is the rate law for the reaction A + A -> B + B?

Back

rate = k[A]^2

Front

How does a catalyst speed up a reaction?

Back

By providing a pathway that has a lower activation energy.

Front

What is NOT a way to speed up a reaction?

Back

Decrease the pressure.

Front

Define reaction order.

Back

The power to which the concentration of a reactant is raised in the rate law.

Front

What is the effect of increasing the concentration of reactants on the rate of a reaction?

Back

It generally increases the rate of the reaction.

Front

What is activation energy?

Back

The minimum energy required for a reaction to occur.

Front

What is a catalyst?

Back

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

Front

Explain the concept of half-life in chemistry.

Back

The time required for half of a sample of a radioactive substance to decay.
