Carbonyl bromide decomposes to carbon monoxide and bromine at 73°C with Kc = 0.190.
COBr2(g) ↔ CO(g) + Br2(g)
Suppose you placed 0.500 mol of COBr2 in a 2.00 liter flask and heated it to 73°C. After equilibrium was reached, suppose you added an additional 2.00 mol of CO to the flask at the same temperature. When equilibrium is re-established, what are the new equilibrium concentrations of COBr2, CO, and Br2?
