The graph of the effect of catalyst on activation energy is given below. Fill up the blanks X and Y with appropriate statements

Options

A. X = energy of activation without catalyst,
Y = energy of activation with catalyst
B. X = path of reaction with catalyst, Y = path of reaction without catalyst
C. X = energy of activation with catalyst,
Y = energy of activation without catalyst
D. X = energy of endothermic reaction, Y = energy of exothermic reaction

Answer

C

Explanation

Energy of activation is lowered when a catalyst is used
