The following reaction has an equilibrium constant Kc equal to 3.59 at 900oC.

For each of the following compositions, decide whether the reaction mixture is at equilibrium. If it is not, decide which direction the reaction should go.
a. [CH4] = 1.26 M, [H2S] = 1.32 M, [CS2] = 1.43 M, [H2] = 1.12 M
b. [CH4] = 1.25 M, [H2S] = 1.52 M, [CS2] = 1.15 M, [H2] = 1.73 M
c. [CH4] = 1.30 M, [H2S] = 1.41 M, [CS2] = 1.10 M, [H2] = 1.20 M
d. [CH4] = 1.56 M, [H2S] = 1.43 M, [CS2] = 1.23 M, [H2] = 1.91 M
