At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3.

Question

H2(g)+I2(g) <-> 2HI(g)

At this temperature, 0.300 mol of H2 and 0.300 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present at equilibrium?

Answer 1

Have you ever used an ICE table?

Here is a great tutorial, but it takes some paying attention.
