c) Sulfur dioxide can be formed from the oxidation of solid sulfur according to Sa+ O2(8) SO2(g) i). Write the equilibrium constant expression for this process. [10 marks) ii) Calculate the change in enthalpy, entropy, and Gibbs energy at 298 K using the following information: AdHº(Sc.)) = 0 kJ mol', S°(S)) = 32.1 J mol K-! A/H" (022)) = 0 kJ mol", S(022)) = 205.07 J mol K! A/H°(CO2(0)) = -393.5 kJ mol"!, S°(CO2(g)) = 213.79 J mol'K! Is this spontaneous at 298 K? (30 marks] iii) How would the following change the equilibrium (towards the reactants, towards the products, or no change)? • Addition of SO2 • Addition of sulfur • Increasing temperature Decreasing pressure
