Reaction quotient

Postby Diana Sandoval 1K » Thu Jan 10, 2019 7:46 pm

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?

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!
