JEE Main Chemistry question
An equilibrium mixture of the reaction 2NO(g) + O₂(g) ⇌ 2NO₂(g) contains 0.120 mole of NO₂, 0.080 mole of NO and 0.640 mole of O₂ in a 4 litre flask at constant temperature. The value of Kc for the reaction at this temperature is:
Answer: (A)
Solution
[NO₂]=0.03,[NO]=0.02,[O₂]=0.16. Kc=(0.03)²/[(0.02)²×0.16]=14.1.
