Problem

The value of Kc for the thermal decomposition of hydrogen sulfide, shown below, is 2.2 x 10-4 at 1400 K.

2H2S(g) ⇌ 2H2(g) + S2(g)

A sample of gas in which [H2S] = 5.20 M is heated to 1400 K in a sealed vessel. After chemical equilibrium has been achieved, what is the value of [H2S]? Assume no Hor S2 was present in the original sample.
