Carbon disulfide is a foul-smelling solvent that dissolves sulfur and other nonpolar substances. It can be made by heating sulfur in an atmosphere of methane. For the reaction below, deltaH=760.4kJ/mol of S8 and deltaS=1219.2 J(K mol of S8). Calculate the equilibrium constant at 230 degrees celcius and at 480 degrees celcius.
4CH4 (g) + S8 (s) <-----> 4CS2 (g) + 8H2 (g)
