### Reaction quotient

I was doing the homework and I came across a problem where the reactants had both gases and liquids and the products were only solid. I am aware the formulas is [products]/[reactants] but in this case do we not use the reactants?

### Re: Reaction quotient

You still have to use the reactants, otherwise you wouldn't have an expression at all! Since the products are all solid, you put a 1 for the numerator. So, your expression for the reaction quotient would be 1/[reactants in gas phase]

If you're pertaining to 11.13a (6th Edition), you use the reactants. The products, since they're solids, are simply 1 in the equation.

If they're not gas, you can use the value of 1 as a replacer

Since the products are not gases, you put a 1 in the numerator. Then place the reactants that are gases in the denominator. Hope this helps!
