Problem

In a

2.00\,\text{L}

reaction vessel at 500 K,

1.50\,\text{mol}

of CO(g) and

2.40\,\text{mol}

of H

_2

(g) are mixed to form methanol according to

\text{CO}(g)+2\,\text{H}_2(g)\rightleftharpoons \text{CH}_3\text{OH}(g)

. When equilibrium is reached, the vessel contains

0.30\,\text{mol}

of CH

_3

OH(g). Calculate the value of

K_c

for this reaction at 500 K.
