At a high temperature, the equilibrium constant for the decomposition of hydrogen iodide is 65.0. If the initial concentration of HI is 1.60 M, what is the concentration of hydrogen at equilibrium?
2Hl(g) H2(g) + I2(g)

A. 1.42 M
B. 0.753 M
C. 0.240 M
D. 0.802 M

I'm actually not sure how to work through this question at all so I don't have any ideas as to which answer it is. Can someone show me how to work through it?

......2HI ==> H2 + I2
I.....1.60.....0....0
C.....-2x......x....x
E....1.60-2x...x....x

Substitutethe E line into the Keq expression and solve for x.
