First, write the equilibrium expression based on the chemical equation:

K_eq = [CH_3OH]^1/[CO]^1[HS^–]^2

Next, plug in the given values:

14.5 = [CH_3OH]/(0.15)(0.36)^2

Solving for [CH_3OH], we get:

[CH_3OH] = K_eq [CO][HS^–]^2

[CH_3OH] = (14.5)(0.15)(0.36)^2

[CH_3OH] = 0.0282 M

Therefore, the equilibrium concentration of CH_3OH is 0.0282 M, which is answer choice C.
