Question

At a given temperature, the equilibrium constant of the reaction H2(g) + I2(g) <->2HI(g) is 9.0. If 1 mol of H2 and 1 mol of I2is introduced into a 1L vessel, what will be the concentration of HI at equilibrium?

Answer 1

Try to start this by setting up an ICE chart, then write the equilibrium law expression.
