Question

Dihydrogen gas is obtained from natural gas by partial oxidation with steam As per following endothermic reaction: 

CH_{4 (g)} + H₂O _(g) ⇌ CO _(g) + 3H_{2 (g)} 

(a) Write as expression for K_p for the above reaction. 

(b) How will the values of K_p and composition of equilibrium mixture be Affected by

(i) increasing the pressure 

(ii) increasing the temperature 

(iii) using a catalyst? 

Answer 1

(a) = [][2 ]³  /  [₄ ][₂] 

(b) (i) Value of K_p will not change, equilibrium will shift in backward direction. 

(ii) Value of K_p will increase and reaction will proceed in forward direction. 

(iii) No effect.
