Problem: For the following reaction, Kp = 8,532 at a given temperature.2 NO(g) + Cl2(g) <=> 2 NOCl(g)At equilibrium, PNO = 0.734 and PCl2 = 0.303. What is the equilibrium partial pressure of NOCl?Give your answer to 3 significant figures.

FREE Expert Solution

We’re being asked to determine the equilibrium partial pressure of NOCl.


We are given the equation: 

2 NO(g) + Cl2(g) ↔ 2 NOCl(g)


Recall that the equilibrium constant is the ratio of the products and reactants

We use Kp when dealing with pressure and Kc when dealing with concentration:


Kp=PproductsPreactants     Kc=[products][reactants]


Note that solid and liquid compounds are ignored in the equilibrium expression.
