Q1. Correct answer is : (c.) Q > Kp, reaction proceeds to the left
Q2. Correct answer is : (a.) cooling the container and increasing the volume
Explanation
Q1. Reaction quotient, Q = [pNO2]2 / [pN2O4]
Q = (2.10 atm)2 / (0.65 atm)
Q = 6.78
Since Q > Kp, therefore, reaction proceeds to the left towards the reactants.
