(c)
For reaction 1 taking place at 120 °C:
Hg0(s) + S02(g) = Hg(l) + S03(g)
Reaction 1
AreactG = -13.6 kJ mol-1
(i) Given the standard Gibbs free energy above for reaction 1, calculate AreactG when the partial
pressures for S0, and SO2 are 1 bar and 0.004, respectively.
(ii) Calculate the equilibrium constant for the reaction and hence state what will be the mole
fraction of SO3 in the gas phase at equilibrium.
Note: In calculation assume K=÷; where the term x is the mole fraction of SO3.
