Equilibrium constant and partial pressures - A-level chemistry question walk through

In this walk through we’ll look at a question involving equilibrium constant in terms of partial pressures. Kp can be used to express the position of an equilibrium quantitatively rather than just saying equilibrium lies to the left or tp the right. I’ll explain how to calculate equilibrium amounts, partial pressures and derive the Kp expression. We will use this expression to calculate a value of Kp with units using the data provided. I the final part of the question I'll show you how Le Chatelier's principle can be used to predict the impact that changing the temperature will have on the value of Kp.
