Increasing Pressure

Postby Rebecca_Arnold_3I » Sun Nov 27, 2016 10:38 pm

Is it true that when the pressure increases, the volume decreases? If this is the case and the pressure of the reaction increases- why does the reaction favor the side with fewer moles of gas and try to move towards that? Thank you!!

The pressure can be increased by decreasing the volume or by adding moles of (inert) gas (Ideal Gas Law: PV=nRT).
The greater the number of moles of gas, the greater the pressure. Thus, when the pressure is increased, the reaction will try to reduce the pressure created by the moles of gas by favoring the side with less moles of gas.
