Question

Estimate the value of the equilibrium constant at 500 K for each of the following reactions.

2H2S(g)⇌2H2(g)+S2(g)

I have calculate my delta H which is 168.9 kj/mol but I don't know where to go from there

Answer 1

Not much to go on here. If you have delta H, I assume the next step is to calculate delta S and delta G.
Then dGrxn = -RTlnK.
