A 0.79 mole sample of HI is placed in a 5.000 liter container
and held at a constant temperature until the gas-phase reaction
2 HI ⇀↽ H2 + I2
comes to equilibrium. At equilibrium, it is found that the
concentration of I2 is 2.1×10−2 mol/L. What is the numerical value
of the equilibrium constant Kc at this temperature?
