How do you calculate partial pressures in an equilibruim equation?

Question

given the mol of everything, liters of container, and the t. i know the formula to get k(c) to k(p), i think that's something different? i dunno, I'm not good at equilibriums thanks.

Answer 1

First add up all the moles of gas. Then divide each number of moles by this total, to get the mole fraction of each gas. Then multiply each mole fraction by the total pressure to get the partial pressures. Then put these into a Kp expression to calculate Kp.
