O KINETICS AND EQUILIBRIUM Setting up a reaction table Suppose a 250. mL flask is filled with 2.0 mol of CO, 1.9 mol of CO, and 1.5 mol of H2. This reaction becomes possible co)+H,0)CO2)+H2) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of H2. You can leave out the M symbol for molarity CO 11,0 CO initial change equilibrium

Explanation / Answer

Molarity of -->

[CO] = 2/0.25 = 8.0 M, [CO2] = 1.9/0.25 = 7.6M, [H2] = 1.5/0.25 = 6.0M

Now, CO + H2O --> CO2 H2

Initial 8 0 7.6 6.0

Change x x -x -x

Eq. 8+x x 7.6-x 6.0-x
