A flask is charged with 1.500 atm of N2O4(g) and 1.00 atm NO2(g) at , and the following equilibrium is achieved:
N2O4(g) → 2 NO2(g)
After equilibrium is reached, the partial pressure of NO2 is 0.512 atm. (a) What is the equilibrium partial pressure of N2O4? (b) Calculate the value of Kp for the reaction.
