Calculate the standard enthalpy change (ΔH°), standard entropy change (ΔS°) and standard Gibbs free energy change (ΔG°) of the reaction:2A(g) + 3B(g) → C(g) + 2D(g)given thatΔH°f[A(g)] = 200 kJ mol^-1Δ H°f [B(g)] = 100 kJ mol^-1Δ H°f [C(g)] = 400 kJ mol^-1Δ H°f [D(g)] = 0 kJ mol^-1ΔH°= -400 kJ mol^-1Temperature (T) = 298 KThe student needs to use their knowledge in quantum chemistry and thermodynamics to calculate the thermodynamic properties of the given reaction.

Calculate the enthalpy change and the entropy change of the reaction where 2 moles of HCl(g) reacts with 1 mole of CaO(s) to produce 1 mole of CaCl2(s) and 1 mole of H2O(l). Given the bond dissociation enthalpies (in kJ/mol) of H-H is 436, Cl-Cl is 243, H-Cl is 431, and O-H is 463. The standard entropies (in J/mol K) of HCl(g) is 186.9, CaO(s) is 38.2, CaCl2(s) is 223.0, and H2O(l) is 69.9.
