Use the diagram above to answer this question. The activation energy of the uncatalysed reaction is
X
X + Y
X - Y
Y
解释
Activation energy is the minimum amount of energy required for a chemical reaction to occur. Graphically, it is the difference between the peak of the hump and the reactant energy.
Consequently, the correct answer is option A.
