Answer to Question #139327 in Physical Chemistry for Lisa

Question

1) The equilibrium constant for the reaction

I2 (s) + Br2 (g) <-- --> 2 IBr (g)



is 0.164 at 25 °C.



(a)Calculate ΔG°rxn for this reaction



(b)Bromine gas is introduced into a container with excess solid iodine. The pressure and temperature are held at 0.164 atm and 25°C, respectively. Find the partial pressure of IBr (g) at equilibrium. Assume that all the bromine is in the gas form and that the vapor pressure of iodine is negligible.
