Normally due to H^{+} being the reference state in solution, all 'standard molar' state variables and 'standard value of formation' state variables are 0 for it. But H_{2}(g) has a standard enthalpy of formation = 0 and standard molar entropy of 115 Jmol^{1}K^{1}. Then shouldn't ΔG°(298) for the reaction
2H^{+}(aq) + 2e^{} = H_{2}(g) be 34,720 J and K = 1 * 10^{6}, E°=+0.1799? But I thought according to electrochemistry that E°=ΔG°=0 for this reaction and thus K=1.
