JEE Main 2022 Chemistry question
At 600 K, 2 mol of NO are mixed with 1 mol of . The reaction occurring as above comes to equilibrium under a total pressure of 1 atm. Analysis of the system shows that 0.6 mol of oxygen are present at equilibrium. The equilibrium constant for the reaction is . (Nearest integer)
Answer: 2
Solution
At equilibrium mol (0.4 mol reacted), so NO = 2 − 0.8 = 1.2 mol and mol, a total of 2.6 mol. The partial pressures are = 1.2/2.6,
