The equilibrium constant for the reaction H2+122HI Is 20 at 40 °C, and the vapor pressure of solid iodine is 0.1 bar at that temp. If 12.7 g of solid iodine are placed in a 10-dm³ vessel at 40 °C, what is the minimum amount of hydrogen gas that must be introduced in order to remove all the solid iodine?
