Explanation Write the stoichiometric reaction for the dissociation process. CO+ 1 2 O 2 ⇌ CO 2 (I) From Equation (1), infer that the stoichiometric coefficients for carbon monoxide ( v CO ) is 1, for oxygen ( v O 2 ) is 0.5, and for carbon dioxide ( v CO 2 ) is 1 respectively. Write the actual reaction for the dissociation process. CO+3O 2 → x CO 2 + y CO + z O 2 (II) From Equation (2), infer that the equilibrium composition contains x kmol of CO 2 ( N CO 2 ) , y kmol of CO ( N CO ) , and z kmol of O 2 ( N O 2 ) . Write the formula for total number of moles ( N t o t a l ) . N t o t a l = N CO 2 + N CO + N O 2 (III) Here, number of moles of CO 2 is N CO 2 , number of moles of CO is N CO , and number of moles of O 2 is N O 2 . Write the equilibrium constant ( k p ) for the dissociation process. k p = N CO 2 v CO 2 N CO v CO N O 2 v O 2 ( P N t o t a l ) ( v CO 2 − v CO − v O 2 ) (IV) Here, pressure is P . Conclusion: From Equation (2), write the carbon balance equation. 1 = x + y y = 1 − x (V) From Equation (2), write the oxygen balance equation. 7 = 2 x + y + 2 z 7 = 2 x + ( 1 − x ) + 2 z z = 3 − 0
