$A\,\xrightarrow[{1200\,\,atm}]{{470\,\,K}}B$
$A\,\xrightarrow[{C{O_2}\, - \,atm}]{{570\,\,K}}C$
$NH_4HS(s) \rightleftharpoons NH_3(g)+H_2S(g)$
is following to set up at $127\,^oC$ in a closed vessel. The total pressure at equilibrium was $20\,atm$ . The $K_C$ for the reaction is
$C{S_2}(g)\, + 4{H_2}(g) \rightleftharpoons \,C{H_4}(g)\, + \,2{H_2}S(g)$
