For the reaction N2O4(g) <=> 2NO2(g), Kc = 20.4 and Kp = 600.1. Treating all gases as ideal with R = 0.0831 L bar K⁻¹ mol⁻¹, the temperature is ______ K (nearest integer).

  1. 354
  2. 300
  3. 404
  4. 273

Correct answer: 354

Solution

Since delta n = 1, T = Kp/(Kc*R) = 600.1/(20.4 * 0.0831) ~= 354 K.
