First, write out the equilibrium expression for the reaction:

K_eq = [CHSOH][H2S]/[CO]

We are given the equilibrium concentrations of CO and H2S, so we can substitute those values into the expression:

K_eq = [CHSOH][0.36^2]/[0.15] = 14.5

Solving for [CHSOH], we get:

[CHSOH] = K_eq*[CO]/[H2S]^2 = 2.82 × 10^-11 M ≈ 2.82 × 10^-11 mol/L

Therefore, the equilibrium concentration of CHSOH is approximately 2.82 × 10^-11 M or 2.82 × 10^-11 mol/L. The correct answer is C.
