Answer to Question #9729 in Physical Chemistry for Sandra
How do you calculate the kp of the reaction N2O4(g)<-->2NO2(g) if 0.01262M of NO2 are made at 723 mmHg and 298K?
Kp = Kc(RT)
Kc = [NO2]2/[N2O4]
[N2O4] is unknown.
In the case when the concentration [N2O4] is known, the constant will have the form
Kp = [NO2]2/[N2O4] * (RT)
Kp = (0.01262)2/[N2O4] * 8.31*298
