# Finding the equilibrium concentration of IBr, I2, and Br2?

I have been working on this problem for an hour or so now, and I'm down to one attempt remaining. I really want to understand how to work this for an upcoming test, but I can't seem to grasp the concept working it on my own. Thanks in advance!
For the reaction I2(g)+Br2(g)←−→2IBr(g), Kc=280 at 150 ∘C....

For the reaction I2(g)+Br2(g)←−→2IBr(g), Kc=280 at 150 ∘C. Suppose that 0.550 mol IBr in a 2.00-L flask is allowed to reach equilibrium at 150 ∘C.

Part A

What is the equilibrium of IBr?

Part B

What is the equilibrium of I2?

Part C

What is the equilibrium of Br2?
