Question

which curve on the energy diagram shows the reaction that ran slower? solid gray curve, because it has a higher activation energy solid gray curve, because it has a lower activation energy dotted blue curve, because it has a higher activation energy dotted blue curve, because it has a lower activation energy

Explanation:

The rate of a chemical reaction is inversely related to the activation energy. Higher activation energy means fewer reactant molecules have enough energy to overcome the energy - barrier and react, resulting in a slower reaction. The solid gray curve has a higher peak (activation energy) compared to the dotted blue curve on the energy - diagram.

Answer:

Solid gray curve, because it has a higher activation energy
