The energy of activation for the decomposition of 2 mol of HI to H 2 and I

Question:

The energy of activation for the decomposition of 2 mol of HI to H₂ and I₂ in the gas phase is 185 kJ. The heat of formation of HI(g) from H₂( g) and I₂( g) is -5.65 kJ/mol. Find the energy of activation for the reaction of 1 mol of H₂ and 1 mol of I₂ to form 2 mol of HI in the gas phase.
