Yes, friends, the Keq expression! We know the value of Keq (55.6 in this case), so we plug the values from the table into the Keq expression and solve for x! H2 + I2 2HI. Plugging in values for equilibrium concentrations from the [E] row of the ICE Table: This looks an awful lot like a quadratic, but relax!
