Hey guys please give me the answers quickly I need it so quick I will give you a good rate thank you

b. 7.7 x 105 C. 2.2 x 10-1 d. 4.6 e. 1.3 x 104 13. A study of the system XRreal - Xial + Brela), was carried out. A container + Br2(g), was carried out. A container was charged initially with an (XBr2] = 2.00 mol/L as the only component. The system was allo come to equilibrium. If Kc = 4.0 x 10-4 what was the concentration of X(g) at equmonum a. 0.000056 M b. 0.00020 M c. 0.00028 M d. 0.000000040 M e. 0.000000080 M 14. A study of the system, 4 NH3(g) + 7 O2(g) = 2 N204(9) + 6 H2O(g), was carried out. A system was prepared with (NH3] = [O2) = 3.60 M as the only components initially. At equilibrium, (N204] is 0.60 M. Calculate the value of the equilibrium constant, Ke, for the reaction. a. 8.10 b. 0.00000930 c. 0.300 d. 0.0216 e. 3.33 15. The two steps in the reaction which takes place in breeder reactors is
