When the reaction below is at equilibrium there are 0.250 mol of Br2, 1.25 mol of Cl2, and 1.5 mol of BrCl in a closed flask of 1.00 L at 100 degrees C. A Chem 109 student upsets the equilibrium by adding 0.0500 mol of Br2 into the 1L sealed flask. The equilibrium constant for the reaction is Kc = 7.20 at 100 degrees C. Calculate the concentration of Br2, Cl2 and BrCl when the new equilibrium is established. Br2 (g) + Cl2 (g)   <--->   2 BrCl (g)                         Kc = 7.20 at 100 degrees C

Question

When the reaction below is at equilibrium there are 0.250 mol of Br2, 1.25 mol of Cl2, and 1.5 mol of BrCl in a closed flask of 1.00 L at 100 degrees C. A Chem 109 student upsets the equilibrium by adding 0.0500 mol of Br2 into the 1L sealed flask. The equilibrium constant for the reaction is Kc = 7.20 at 100 degrees C. Calculate the concentration of Br2, Cl2 and BrCl when the new equilibrium is established.

Br2 (g) + Cl2 (g)   <--->   2 BrCl (g)                         Kc = 7.20 at 100 degrees C
