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

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