For the equilibrium 2h2s(g)=2h2(g)+s2(g) Kc=9.0x10^-8 at 700 degree cl the initial concerntration of the three gases are 0.270M h2s,0.270 h2 and 0.135 s2. determine the equilibrium concentrations of the three gases
When the reaction 2H2S(g)-> 2H2(g) + S2(g) is carried out at 1065°C, Kp = 0.012. Starting with pure H2S at 1065°, what must the initial pressure of H2S be.
