Question

The equilibrium constant, K, for the following reaction is 1.80×10-2 at 698 K. 2HI(g) H2(g) + I2(g) An equilibrium mixture of the three gases in a 1.00 L flask at 698 K contains 0.325 M HI, 4.36×10-2 M H2 and 4.36×10-2 M I2. What will be the concentrations of the three gases once equilibrium has been reestablished, if 2.27×10-2 mol of I2(g) is added to the flask?

[HI] = _____M

[H2] = ____M

[I2] = _____M
