The industrial solvent carbon disulfide can be made from the reaction between methane and hydrogen sulfide at elevated temperatures using the following reaction gas-phase reaction: 

a. Compute the equilibrium constant for this reaction from 500 to 800°C. 

b. Starting with equal number of moles of H₂S and CH₄, compute the equilibrium compositions of all components in the reaction at 1 bar and over the temperature range of part (a). 

c. Repeat the calculation of part (b) for a pressure of 10 bar. Ideal gas mixture behavior may be assumed at this pressure at these high temperatures.
