The activation energy for the forward and the one for the reverse
reaction are similar because they attained chemical equilibrium. A chemical
equilibrium happens when both of the reactant and products achieve the same
concentration.
Step-by-step explanation:
Since the triangles are right angled and are similar,
by Pythagoras theorem,
(10√3)^2 = (5√3)^2 + a^2
a = 15, a > 0
