Task:

Suppose that the molar concentrations for CO and H₂ at equilibrium are [CO] = 0.05 M and [H₂] = 0.06 M.

Use the formula you found in Part B to calculate the concentration of CH₃OH.

Formula from part B: Kc[CO][H₂]²

Answer:

CO + 2H₂ = CH₃OH

Kc = [CH₃OH]/[CO][H₂]²

[CH₃OH] = Kc × [CO][H₂]²

The equilibrium constant for the given recation is Kc = 2.3*10⁴.

[CH₃OH] = 2.3*10⁴ × 0.05 × 0.062 = 4.14 M
