# Problem: The activation energy for some reaction X2 (g) + Y2 (g) → 2XY (g)is 167 kJ/mol, and ΔE for the reaction is 128 kJ/mol. What is the activation energy for the decomposition of XY?

###### FREE Expert Solution

Recall that for energy diagrams: If we need to calculate for the EA of the decomposition reaction (reverse reaction), we just have to take the difference of ΔE or ΔH and the EA of the forward reaction
