Thermodynamic ΔH -25.0 kJ/mol

The catalyst lowers the transition state activation energy barrier ($E_a$) from 75.0 kJ/mol down to 32.5 kJ/mol, accelerating forward and reverse rate constants equally while leaving overall thermodynamic equilibrium ($\Delta H = -25 \text{ kJ/mol}$) completely invariant.
