Suppose the provided unknown Q was a solution of 6.732 M Fe2+ and a concentration cell was constructed with one half-cell containing the provided unknown Q solution and an iron electrode, and the other half-cell containing a diluted unknown Q solution (diluted using the procedure listed in Part A) and an iron electrode, as shown below.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
