WebbC2H6(g) H2(g) + C2H4(g) Answer: ΔG° = 102.0 kJ/mol; the reaction is nonspontaneous ( not spontaneous) at 25 °C. The standard free energy change for a reaction may also be … WebbIt is assumed that the gas phase is a perfect gas. As the standard entropy is zero, i.e. S=0, only enthalpy is relevant. The standard enthalpy of formation of a compound is the sum …
