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?

🤓 Based on our data, we think this question is relevant for Professor Perrin's class at UCSD.

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
