2ClF3(s) <--> Cl2(g) + 3F2(g)
In order to establish the equilibrium, 5.45g of ClF3(s) was placed into a 500mL flask. When the equilibrium was established the Cl2(g) was measured at 0.0280 mol/L.
The equilibrium contant for the equilibrium above is a.bc*10-d. The values of a,b,c and d are.

Consider: Cl 2 (g) + PCl (g) ↔ PCl 5 (g)
Initial [ ]’s of Cl 2 and PCl 3 are shown in the following data table and the concentration changes
are recorded at various time periods after the reaction progresses towards equilibrium.
Reaction time (sec) [Cl 2 ] mol/L [PCl 3 ] mol/L [PCl 5 ] mol/L
0 1.00 1.00 0.00
20 0.90 0.90 0.10
40 0.80 0.80 0.20
60 0.75 0.75 0.25
80 0.71 0.71 0.29
100 0.71 0.71 0.29
120 0.71 0.71 0.29
From observing this data table:

John has written the following proof showing that the diagonals of a parallelogram are equal in length. The diagonals of a parallelogram are not necessarily equal, so he must have made an error. Identify and explain the error.
