It has a rate that is independent of the activation energy for the reaction.

It determines the value of the standard enthalpy of reaction for the reaction.

It almost always involves the breaking of hydrogen bonds.

It limits the effectiveness of a catalyst.

It controls the rate at which the products are produced.

changing the products formed in the reaction

providing an alternate pathway which has a different activation energy

always providing a surface on which molecules react

changing the enthalpy of reaction for the reaction

changing the frequency of collisions between molecules

The value for the enthalpy of reaction would be decreased by addition of a catalyst.

The reaction rate would be decreased by an increase in temperature.

The reaction is endothermic.

The reverse reaction is slower than the forward reaction (smaller rate constant).

The addition of a catalyst will produce a change in magnitude of the activation energy which is greater for the forward reaction than the reverse reaction.
