$\Delta H = -32.7\,Kcal$ carried out is a vessel, the equilibrium concentration of $C_2H_4$ can be increased by
(Molar mass of $Ca(OH)_2, Na_2SO_4$ and $CaSO_4$ are $74, 143$ and $136\, g\, mol^{-1}$ respectively; $K_{sp}$ of $Ca(OH)_2$ is $5.5 \times 10^{-6}$)
If dilute $HCl$ is added to an aqueous solution of ${H_2}S$ without any change in temperature
