The equilibrum constant Kc is 0.01323 for the reaction: CCl4 (g) <----> C(s) + 2 Cl2 (g)

At 300k a 5L flask originally contained 0.0828M of CCl4, 0.0444 M of C and 0.0546M of Cl2. Determine the concentration of Cl2 when equilibrium is reached.

Solutions

Expert Solution

                 CCl4 (g) <----> C(s)    + 2 Cl2 (g)   

I 0.0828    0.0444      0.0546

C            +x                       -x              -x

E            0.0828+x          0.0444-x    0.0546-x

Kc   = [Cl2]^2/[CCl4]

0.01323    = (0.0546-x)^2/0.0828+x

0.01323(0.0828+x) = (0.0546-x)^2

    x   = 0.018

[Cl2]   = 0.0546-x = 0.0546-0.018   = 0.0366M >>>>>answer
