Question

For a one step reaction, the activation energy for the forward reaction is 40.0 kJ mol -1 , and the enthalpy of reaction is -20.0 kJ mol -1 .  Which statement below is true?

Accepted Answer

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

Answer

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

Answer

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

Answer

The reaction is endothermic.

Answer

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.
