At 430 degree C, the equilibrium constant (Kp) for the reaction 2NO(g) + O2(g) 2

Question

At 430 degree C, the equilibrium constant (Kp) for the reaction 2NO(g) + O2(g) 2NO2(g) is 1.5 x 10^5. In one experiment, the initial pressures of NO, O2, and NO2 are 7.1 x 10^-3 atm, 9.2 x 10^-2 atm, and 0.11 atm, respectively. Calculate Qp and predict the direction that the net reaction will shift to reach equilibrium. What is Qp for the experiment? In which direction will the system proceed to reach equilibrium? The reaction will proceed to the left. The reaction is at equilibrium. The reaction will proceed to the right.

Explanation / Answer

Qp= 2609

direction =towards left as Qp< Kp
