pressure and volume

Postby Alyssa Bryan 3F » Sun Jan 20, 2019 8:57 pm

Can someone explain the relationship between pressure and volume for Le Chatelier's Principle.

As pressure increases, volume decreases, which causes the concentration of reactants and products to change. This change makes the system not in equilibrium, and therefore causes movement towards equilibrium.

Volume and pressure are inversely related.

Looking at PV=nRT you can see that pressure and volume are inversely related. An increase in pressure results in a decrease in volume. And a decrease in pressure results in an increase in volume.

Only a change in pressure that is caused by a change in volume affects the direction of the reaction because for an increase in volume, for example, causes a decrease in pressure (PV=nRT) and consequently a change in concentration. On the other hand, if the pressure changes because extra inert gases were added, then the direction of the reaction will not change because there is no change in concentration.

Pressure and volume are inversely related! For example, if pressure decreases, volume goes up, and vice versa.
