The equilibrium constant at constant pressure, Kp for the reaction,
2NO(g) + Cl₂(g) → 2NOCl(g) is 800. The partial pressures of the gas mixture at equilibrium are 0.02 atm each for NO and Cl₂. What is the partial pressure of NOCl in the mixture?

• A.0.02 atm
• B.6.41 x 10^-4 atm
• C.0.04 atm
• D.0.08 atm
