Review Powerpoint Partial pressure

[asannajust_1J]

for the problem that asks to solve for the partial pressures of each gas PCl3 + Cl2 =PCl5 .. I found the value of K=10 but was not sure how he got the ratio of 2x/x^2 . Can someone please explain this?

According to the question, the partial pressure of the reactants was equal to half the products so each reactant would be equivalent to x and the product would be 2x. When you multiply the reactants and do products over reactants you get 2x/x^2.
