Problem 10.52 Review Consta The K, for the following reaction is 15 at 220 °C. CO(g) + 2H2(g) + CH, OH(9) Part A If an equilibrium mixture contains 0.43 M CO and 0.24 M H2, what is the molar concentration of CH, OH? Express your answer to two significant figures and include the appropriate units. HÁRO? Value Units CH, OH - Submit Request Answer Provide Feedback

Answer 1

From the balanced reaction

K_c = _{$\frac{[CH_{3}OH]}{[H_{2}]^{2}[CO]}$}

Given , [CO] = 0.43 M

[H₂] = 0.24 M  

Kc = 15

Then,

[CH₃OH] = Kc $\times$ [H₂]²$\times$   [CO] = 15 $\times$ (0.24)²$\times$ (0.43)

or, [CH₃OH] = 0.37 M
