Suppose that the molar concentrations for CO and H2 at equilibrium are [CO] = 0.03 M and [H2] = 0.04 M. Use the formula [CH3OH]= Kc[CO][H2]2 calculate the concentration of CH3OH. Express your answer to one decimal place and include the appropriate units.

Answer:

[CH₃OH] = 1.1 M

Explanation:

Let's consider the synthesis of methanol at high temperature.

CO(g) + 2 H₂(g) ⇄ CH₃OH(g)

The equilibrium constant Kc is:

[tex]Kc=\frac{[CH_{3}OH]}{[CO].[H_{2}]^{2} }[/tex]

We know the concentrations at equilibrium, [CO] = 0.03M and [H₂] = 0.04 M. So, we can find [CH₃OH].

[tex][CH_{3}OH]=Kc.[CO].[H_{2}]^{2} =2.3 \times 10^{4} \times 0.03 \times 0.04^{2} =1.1M[/tex]
