0.50 mol of I2(g)\text{I}_2(\text{g}) and 0.50 mol of Br2(g)\text{Br}_2(\text{g}) are placed in a closed flask. The following equilibrium is established. I2(g)+Br2(g)⇌2IBr(g)\text{I}_2(\text{g}) + \text{Br}_2(\text{g}) \rightleftharpoons 2\text{IBr}(\text{g}) The equilibrium mixture contains 0.80 mol of IBr(g)\text{IBr}(\text{g}) . What is the value of KK ?
