what is the relationship between the equilibrium constant Kc and the equilibrium pressure constant Kp? I am given many questions that either give Kc and ask for partial pressures of gases or vice versa. what is the best way to approach these questions?(adsbygoogle = window.adsbygoogle || []).push({});

another question states given this equation:

SO2 + NO2 --> SO3 + NO

Kc=2.9

how much NO2 must be added to 2.2 mol of SO2 to make 1.3 mol of SO3 and equilibrium? I just dont know how to start this. any help would be appreciated. thanks.
