Solution: The value of Kc for the reaction:N2O4 (g) ⇌ 2NO2 (g)is 0.53 at 461.5 K. Part 1 If a reaction vessel at that temperature initially contains 0.0251 MNO2 and 0.0251 MN2O4, what is the concentration of NO

Problem

The value of Kc for the reaction:

N2O4 (g) ⇌ 2NO2 (g)

is 0.53 at 461.5 K. 

Part 1 

If a reaction vessel at that temperature initially contains 0.0251 MNO2 and 0.0251 MN2O4, what is the concentration of NO2 at equilibrium?

Part 2

What is the concentration of N2Oat equilibrium?
