The number of moles of water that have reacted are

\frac{1 \times 40}{100} = 0.4 m o l

Moles of water unreacted are

1.0 - 0.4 = 0.6

mol.

0.4 moles of water reacts with 0.4 mole of CO to form 0.4 moles of hydrogen and 0.4 moles of carbon dioxide.

The equilibrium molar concentrations are:

[H_{2}] = \frac{0.4}{10} = 0.04 M

[C O_{2}] = \frac{0.4}{10} = 0.04 M

[H_{2} O] = \frac{0.6}{10} = 0.06 M

[CO] = \frac{0.6}{10} = 0.06 M

The equilibrium constant is

K = \frac{[ H _{2} ] [ C O _{2} ]}{[ H _{2} O ] [ CO ]} = \frac{0.04 \times 0.04}{0.06 \times 0.06} = 0.444
