6. What is the equilibrium concentration for Cl2(g) in the reaction below if at equilibrium, PCS the M, [PCb]=0.42 M and Ke=0.44? PCIs(g) PC, (g) + Cl2(g) 7. -C that had a Kc value of 2.30 x 10, and you had another Suppose you had a reaction (1) A + B reaction (2) D + E F that had a Kc of 3.00 × 10-2. a. In which reaction is equilibrium established where most of the molecules are reactant molecules? DHE-, Could you determine anything about the relative speed (i.e. rates) of the forward reactions? If so, what, and if not, why not? b. is muene Compar

Explanation / Answer

6)

[PCl5] = 0.40 M

[PCl3] = 0.42M

Kc   = 0.44

PCl5 ---------------------> PCl3 + Cl2

Kc = [PCl3][Cl2]/[PCl5]

0.44 = 0.42 x [Cl2] / 0.40

[Cl2] = 0.42 M

equalibrium concentration of Cl2 = 0.42 M
