Front

How is the rate of reaction defined?

Back

The rate of reaction is defined as how fast a reaction occurs.

Front

What effect does increasing the concentration of reactants have on the rate of reaction?

Back

Products will form faster.

Front

What is a catalyst?

Back

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

Front

How does surface area affect the rate of reaction?

Back

Increasing the surface area of reactants increases the rate of reaction.

Front

What is the role of temperature in chemical reactions?

Back

Higher temperatures generally increase the rate of reaction.
