Answer #1

ICE Table:

[CO] [H2] [CH3OH]

initial 1.0 2.0 0

change -1x -2x +1x

equilibrium 1.0-1x 2.0-2x +1x

Given at equilibrium,

[CH3OH] = 0.5

+1x = 0.5

x = 0.5

Equilibrium constant expression is

Kc = [CH3OH]/[CO][H2]^2

Kc = (+1x)/(1.0-1x)(2.0-2x)^2

Kc = (+1*0.5)/(1.0-1*0.5)(2.0-2*0.5)^2

Kc = 1.0

Answer: e
