Consider the energy diagram below. xn. mc012-1.jpg which line indicates a higher reaction rate? a because it has a lower activation energy. b because it has a lower activation energy. a because its mc012-2.jpggrxn is much lower. b because its mc012-3.jpggrxn is much lower.

Answer is: B because it has a lower activation energy.

For all chemical reaction some energy is required and that energy is called activation energy (energy that needs to be absorbed for a chemical reaction to start), activation energy for reaction B is lower that for reaction A.

Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst.

Chemical reactions occur faster with a catalyst because they require less activation energy.
