Question

Consider the above figure for the reaction :

$A+B⟶M+N$

Energy level of $A$ & $B$ is Y + ____ .

Answer 1

We know that, Threshold Energy = Energy of reactants + Activation Energy.

From the given diagram,

Activation Energy = X

Threshold Energy = X+Y+Z

∴ Energy of reactants (A & B) = Y + Z
