Question

1) Iodine and bromine react as shown below:


I2 (g) + Br2 (g)  2IBr

(g).


If 0.531 mol of I2 and 0.531 mol of Br2 are placed into a sealed 1.00 L flask, and at equilibrium the flask contains 0.88 mol of IBr, what is the  value of the equilibrium constant, Keq ? 


(Hint: you will needed to figure out the amounts of each substance at equilibrium using stoichiometry, before you can substitute into the equilibrium expression.)




2) Dinitrogentetraoxide decomposes according to the following equilibrium:


N2O4 (g)  2 NO2 (g) 


A 1.00-L flask is charged with 0.1862 mol  of N2O4. At equilibrium, 0.031 mol of N2O4 remains. What is the value of the equilibrium constant ( Keq ) for this reaction?
