HARD CHEM QUESTION
posted by scilover .
A chemical system within a sealed 1 L reaction vessel is described by the following reversible reaction equation:
2H2S(g) <-->2H2(g) + S2(g)
If the equilibrium constant is 0.000 004 200 at 1103 K find:
the reaction quotient initially.
This makes no sense to me. Reaction quotients are determined by substituting non-equilibrium concns. With a Keq of 4.2E-6 (I assume that is what you meant) we can calculate the equilibrium concns of the three species. I don't see any numbers with which to calculate Qrxn.
