The equilibrium constant Kp for the reaction below at 700°C is 0.76 atm.
CCl4(g) --> C(s) + 2 Cl2(g)

Determine the initial pressure of carbon tetrachloride that will produce a total equilibrium pressure of 1.20 atm at 700°C

  • Chemistry -

    ...........CCl4 ==> C + 2Cl2
    initial.....x.......0.....0
    change.....-p.............+2p
    equil......x-p............2p
    x-p = 1.2
    0.76 = pCl2^2/pCCl4 = 2p^2/1.2
    Solve for p then p+1.2 = x
