reaction kinetics

Front

What happens to the reaction rate when concentration decreases?

Back

Decreases reaction rate.

Front

Why does a higher temperature increase the rate of a reaction?

Back

It increases both the frequency and energy of particle collisions.

Front

What does more collisions correspond to in a reaction?

Back

Faster reaction rate.

Front

What is the unit for rate constant, K, in the rate law Rate = K [A]?

Back

s^-1

Front

How does grinding a seltzer tablet into powder affect the rate of reaction?

Back

Increases the rate of reaction due to increased surface area.

Front

What is reaction kinetics?

Back

The study of the rates of chemical reactions.

Front

What is the effect of temperature on reaction rates?

Back

Higher temperatures generally increase reaction rates.

Front

What is activation energy?

Back

The minimum energy required for a reaction to occur.

Front

What role do catalysts play in reactions?

Back

They speed up reactions without being consumed.

Front

What is a reactant?

Back

A substance that undergoes change in a chemical reaction.
