Hydrogen is prepared commercially by the reaction of methane and water vapor at elevated temperatures. CH₄(????) + H₂O(????) ⇌ 3

sammy [17]

Answer:

6.2846

Explanation:

Given that:-

Concentrations at equilibrium :-

$[CH_4]=0.126\ M$

$[H_2O]= 0.242\ M$

$[CO]= 0.126\ M$

$[H_2]= 1.15\ M$

The equilibrium reaction is:-

$CH_4+H_2O\rightleftharpoons 3H_2+CO$

The expression for equilibrium constant is:

$K_{c}=\frac {\left [ H_2 \right ]^3\left [ CO \right ]}{\left [ CH_4 \right ]\left [ H_2O \right ]}$

Applying the values as:-

$K_c=\frac{1.15^3\times 0.126}{0.126\times 0.242}=6.2846$

The equilibrium constant for the reaction is:- 6.2846
