2H2S(g)<---> 2H2(g) + S2(g) The value of Kc for the thermal decomposition of hydrogen sulfide is 2.2x10^-4 at 1400 K. A sample of gas which [H2S]=3.65 M is heated to 1400 K in a sealed vessel. After chemical equilibrium has been achieved, what is the value of [H2S] in M? Assume no H2 or S2 was present in the original sample.
