9A CHEMISTRY

To increase the rate of a reaction, the number of successful

collisions must be increased.

Catalysts are consumed in a reaction.

A catalyst initiates a reaction.

A catalyst is always written in the overall chemical

equation.

Desorption is the release of product molecules.

A homogeneous catalyst is easier to recover compared to

the heterogeneous type.

Some catalysts may harm the environment.

Producing ammonia in the Haber process is an irreversible

reaction.

Catalysts would not have the exact mass as it had at the

beginning after a reaction.

According to the collision theory, a reaction will only occur

if successful collisions occur.
