• True
• False

A(n) _____ exists in the same physical state as that of the reaction it catalyzes.

• heterogeneous catalyst
• inhibitor
• homogeneous catalyst

A rate law relates

• reaction rate and temperature.
• reaction rate and concentration.
• temperature and concentration
• energy and concentration.

The sequence of steps that occurs in a reaction process is called the

• order of the reaction.
• overall reaction.
• rate law.
• reaction mechanism.

If a collision between molecules is very gentle, the molecules are

• more likely to be oriented favorably.
• less likely to be oriented favorably.
• likely to rebound without reacting.
• likely to react.
