At 500 K, we have the data Substance AH300/(kJ/mol) S3o0/(J/K mol) HI(g) H2(g) I,(g) 32.41 221.63 5.88 145.64 69.75 279.94 One mole of H,.and one mole of I2 are placed in a vessel at 500 K. At this temperature only gases are present and the equilibrium H2(g) + I2(g) 2 HI(g) is established. Calculate K, at 500 K and the mole fraction of HI present at 500 K and 1 atm. What would the mole fraction of HI be at 500 K and 10 atm?
