Among the following the reaction for which δ H = δ E, is — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

δ H = δ E requires δ n_g = 0. (a) δ n_g = +1. (b) $H_2$(g) + $Cl_2$(g) -> 2$HCl$(g): δ n_g = 2 - 2 = 0. (c) δ n_g = +2. (d) δ n_g = -1. Only reaction (b) has δ H = δ E.
