Ques. 1JEE Main 2024, 29 January (Morning Shift)

For the reaction N2O4(g) 2NO2(g), Kp = 0.492 atm at 300 K. Kc for the reaction at same temperature is 10-2. (Given : R = 0.082 L atm mol-1 K-1)

Answer

Solution

Kp = Kc (RT) ng, ng = 2 - 1 = 1

⇒ Kc = KpRT = 0.4920.082 300 = 0.49224.6

= 0.02 = 2 10-2

Answer: 2
