Front

Define activation energy.

Back

The minimum energy required for a reaction to occur.

Front

What is a rate law?

Back

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

Front

Explain the concept of reaction order.

Back

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

Front

What is a catalyst?

Back

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

Front

Define transition state.

Back

A high-energy state during the conversion of reactants to products.
