### 14.37

In part a, to find Q, the book multiplies the reactant concentration of H+(0.075 M) by the reactant partial pressure of H2 (1 bar) divided by the product of the product concentration of H+ (1 M) multiplied by the product partial pressure of H2 (1 bar). Why are we allowed to multiply concentration by partial pressure and don't convert one into the other?

Q has no units (like K) so when you are multiplying and dividing these values, the units end up cancelling out.
