For each reaction, calculate ΔHrxn°, ΔSrxn°, and ΔGrxn° at 25 °C and state whether or not the reaction is spontaneous. If the reacton is not spontaneous, would a change in temperature make it spontaneous? If so, should the temperature be raised or lowered from 25 °C? 2 CH4(g) → C2H6(g) + H2(g) 2 NH3(g) → N2H4(g) + H2(g)
