Answer: The dotted line shows a new potential energy diagram with a shorter activation energy hill than that in the original potential energy diagram.
Explanation:
Activation energy is the extra amount of energy required by the reactants to cross the energy barrier to get converted into products.
When a catalyst is added, it lowers down the activation energy which is shown by a dotted line. As now less energy is required, more of reactants can cross the energy barrier and get converted to products and thus increase the rate of reaction.
A catalyst increases the rate of reaction for both exothermic and endothermic reactions.
