When the activation energy of an exothermic reaction decreases at a given temperature, the reaction rate increases because the number of successful effective collisions is higher. More of the reactants collide and are able to form products. Hope this answers the question. have a nice day.

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative.
