The "REVERSIBLE" chemical reaction-
A + B <--> C + D
Kc = CD / AB =4.4

Concentration at the start and after equilibrium-
A = 1.00 M --> (1.00 - X) M
B = 2.00 M --> (2.00 - X) M
C = 0.00 M --> X M
D = 0.00 M --> X M
4.4 = X^2 / (1.00-X)(2.00 - X)

• chemistry -

You solve for x. I think you use the FOIL method

• chemistry -

The chemistry is right. It's an algebra problem now. Solve for X. Chopsticks is right. Expand the denominator by using FOIL, gather terms and solve the quadratic equation.
