Explanation Write the expression for total number of moles ( N t o t a l ) . N t o t a l = N N 2 + N O 2 + N NO (I) Here, number of moles of N 2 is N N 2 , number of moles of O 2 is N O 2 , and number of moles of NO is N NO . Write the equilibrium constant ( k p ) for the reported process. k p = N NO v NO N N 2 v N 2 N O 2 v O 2 ( P N t o t a l ) ( v NO − v N 2 − v O 2 ) (II) Here, pressure is P . Write the mole fraction of NO ( y NO ) . y NO = N NO N t o t a l (III) Conclusion: Write the stoichiometric reaction for the reported process. N 2 +O 2 ⇌ 2 NO (IV) From Equation (IV), infer that the stoichiometric coefficient for nitrogen ( v N 2 ) is 1, for oxygen ( v O 2 ) is 1, and for NO ( v NO ) is 2. Write the actual reaction for the dissociation process. N 2 +O 2 → x N 2 + y O 2 + z NO (V) From Equation (V), infer that the equilibrium composition contains x kmol of N 2 ( N N 2 ) , y kmol of O 2 ( N O 2 ) , and z kmol of NO ( N NO ) . From Equation (V), write the nitrogen balance equation. 2 = 2 x + z z = 2 − 2 x (VI) From Equation (V), write the oxygen balance equation. 2 = 2 y + z Substitute 2 − 2 x for z
