Dinitrogen tetroxide was allowed to reach equilibrium with nitrogen dioxide in a 2.00 L flask at 298 K. The equilibrium partial pressures were
PN2O4=0.250atm and PNO2=0.298atm. The flask was then quickly transferred to a 350 K oven; at this higher temperature the equilibrium constant is Kp=1.21, but the partial pressures listed above remained momentarily unchanged at the instant of transfer.
(a) Calculate the reaction quotient Qp immediately after the temperature change using the momentary partial pressures.
(b) Compare Qp with the new value of Kp at 350 K and predict the direction of the net reaction as the system approaches its new equilibrium. Justify your answer.
(c) Indicate whether the partial pressure of N2O4 will increase, decrease, or remain unchanged once the new equilibrium is reached, and explain.
