Question

If a catalyst lowers the activation energy, what raises the activation energy?

Answer 1

Answer: heat or A

Explanation: in order to have higher activation energy you need something to give it that energy. So something like fire would do a great job

Answer 2

you could lower the temperature which would increase the activation enrgy for most reactions

Step-by-step explanation:

not sure why you would want a reaction to have a higher activiation energy but lowering the temperature would mean that more energy would be required of a reaction to begin
