The activation energy E_a, of a reaction is - 5 kJ mol^-1; this suggests that temperature has no effect on the rate constant k, of the reaction.

Question

Quizplus · Accepted Answer

The negative activation energy implies that the reaction is exothermic, and temperature does have an effect on the rate constant. As the temperature increases, the rate constant also increases due to more collisions between reactant molecules, leading to a higher probability of successful collisions.
