The chemical equation for the reaction between methane and elemental chlorine is:
CH4(g) + 2 Cl2(g) → CCl4(g) + 4 HCl(g)
Use the provided values for enthalpies of formation and entropies of the reactants and the products to calculate the standard enthalpy, the entropy and the free Gibbs energy changes associated with the reaction (ΔrHo, ΔrSo, ΔrGo) and tell which one of the statements below describes the reaction correctly
Substance | ΔrHo(kJ/mol) | So(J/molK) |
CH4(g) | -74.9 | 186.2 |
Cl2(g) | 0 | 223.0 |
CCl4(g) | -95.98 | 309.7 |
HCl(g) | -92.30 |
186.9 |
