(A) X (B) Y (C) Z (D) Z - Y

Tardigrade Admin · Accepted Answer

The energy required to initiate a reaction is known as the activation energy, Ea. The bold curve shows the uncatalysed reaction with E a = Z, whilst Y represents the Ea of the catalysed reaction (dotted curve). The Ea is thus lowered by ( Z - Y ).

The energy required to initiate a reaction is known as the activation energy, $E_{a}$ . The bold curve shows the uncatalysed reaction with $E_{a} = Z$ , whilst $Y$ represents the $E a$ of the catalysed reaction (dotted curve). The $E a$ is thus lowered by $(Z - Y)$ .
