Homework Statement
Keq at a given temperature is 4
2 HF (g) <--> H2 (g) + F2 (g)
A 1 Litre jar contains 0.045 moles of fluorine at equilibrium. What was the initial quantity of hydrogen fluoride in the reaction jar?
2. The attempt at a solution
I set the initial concentration of hydrogen fluoride as x, and filled in the attached ICE table.
Afterwards:
4 = (0.045)(0.045) / (x-0.09)^2
x = 0.1125 and 0.0675
Therefore, the final answer is 0.1125 M
