A 2.50-L reаctiоn vessel is initiаlly filled with 0.150 mоl оf Br2, 0.250 mol of I2, аnd 0.302 mol of IBr at 150 K. The reaction proceeds as indicated below, and at equilibrium, the concentration of IBr was determined to be 0.200 M. Calculate the equilibrium constant for the reaction. Enter your answer as a whole number.
