A flask is charged with 1.350 atm of N 2 O 4 ( g ) and 1.14 atm NO 2 ( g ) at 25°C. The equilibrium reaction is given in the equation below. N 2 O 4 ( g )  2NO 2 ( g ) After equilibrium is reached, the partial pressure of NO 2 is 0.512 atm. (a) What is the equilibrium partial pressure of N 2 O 4 ? _____ atm (b) Calculate the value of K p for the reaction. (c) Is there sufficient information to calculate K c for the reaction? If K c can be calculated, find the value of K c .
