### Solve for Q

How do you solve for Q when you aren't given E?
asking from test 2 #8b... or do you just divide the moralities given? if so i got 1.5*10^5 is that correct?

### Re: Solve for Q

Q = [concentration of products] / [concentration of reactants]

Because the molarities/partial pressures of all of the components in the Q equation are given, you simply plug and chug. I believe we may have a different test version so I did not get the same answer as you.

### Re: Solve for Q

It is the concentrations of the products divided by the concentration of the reactants
