Pressure in calculating Q

Postby Lucia H 2L » Thu Feb 22, 2018 10:18 pm

How does pressure affect the calculation of Q? Is the equation different than just [P]^n/[R]^n ?

I think Q is still calculated the same, but instead of using concentrations you are using pressures.

make sure when you are given the concentrations or pressure that they are the same units!

If you remember from 14A as long as we are studying something in a gaseous state we can use partial pressure or concentration to calculate Q since the pressure of gas will also affect the reaction direction.

When calculating Q for a reaction consisting of gases, Molarity and partial pressures are used.
