Question

1.       Consider the balanced reaction:  (note:  D = delta symbol)

2ClF3(g) -> Cl2(g) + 3 F2(g)

Complete the following Table:

            D[ClF3]/Dt                                D[Cl2]/Dt                          D[F2]/Dt

Explanation / Answer

for the reaction rate = -(1/2) d ClF3/dt = dCl2 //dt = ( 1/3) d F2/dt

if dCl2/dt = 0.024 then dClF3/dt = ( -0.024 x 2) = -0.048

and dF2/dt = ( 0.024 x3) = 0.072
