Question

A 5.0L reaction flask initially contains 0.030 mol sulfuryl chloride at 177°C. Sulfur dioxide and chlorine form: SO2Cl2(g) <---> SO2(g) +Cl2(g). After equilibrium is established, chemical analysis shows that 0.0010 mol sulfuryl chloride remains:    a. Calculate the concentration of all species at equilibrium. b. Calculate Kc A 5.0L reaction flask initially contains 0.030 mol sulfuryl chloride at 177°C. Sulfur dioxide and chlorine form: SO2Cl2(g) <---> SO2(g) +Cl2(g).

Explanation / Answer

                         SO2Cl2(g) <---> SO2(g) +Cl2(g)
initially                   (0.03/5)        0         0
at equilibrium      (0.03/5) - x             x         x
(0.03/5 - x) = 0.001/5 = [SO2Cl2] = 0.0002
x = 0.0058 = [SO2] = [Cl2]
Kc = (0.0058)(0.0058)/(0.001/5) = 0.1682
