Suppose once again we have the following exostobic reaction. And now, suppose we try to increase our pressure at constant temperature, so we decrease our volume. And so, the pressure of our system, the pressure of the molecules exert on the wall of the container increases. So what will happen? Well, increasing, or according to Lush of Global principle, increasing pressure by decreasing volume at constant temperature, by making our system smaller, by shrinking, it will shift the equilibrium in a direction where there are less molecules present. In other words, let's see how many molecules we have on the reactant side and how many molecules we have on the product side.
