Changing partial pressure of components vs changing pressure of system

Postby Isabelle Fontanilla 1I » Sun Jan 20, 2019 9:34 pm

Will there be a difference in effects if the pressure of the entire system is changed instead of changing only the partial pressure of the components of the system?

Changing the pressure of the reaction vessel will drive the reaction in the direction where the number of molecules will decrease. If pressure is increased by compression and there are more moles of gas on the left, the reaction will shift right.

If pressure increases then that means volume decreases, so reaction will shift toward the side with less gas moles.
