Question

From information in the Resource section, calculate the standard Gibbs energy and the equilibrium constant at (i) 25 °C and (ii) 50 °C for the reaction CH₄(g) + 3 Cl₂(g) ⇋ CHCl₃(l) + 3 HCl(g). Assume that the standard reaction enthalpy is independent of temperature. At 298.15 K Δ_fG^⦵ (CHCl₃(l)) = −73.7 kJ mol⁻¹ and Δ_fH^⦵ (CHCl₃(l)) = −134.1 kJ mol⁻¹.
