Given
N2(g) + O2(g) รขยย 2NO(g) Kc1 = 1.0 x 10-30
N2(g) + Br2(g) + O2(g) รขยย 2NOBr(g) Kc2 = 2.0 x 10-27
(a) What is the Kc for the reaction: 2NO(g) + Br2(g) รขยย 2NOBr (g)? รยHo = รขยย 47.14 kJ
(b) If you start with [NO] = 5.0 x10-3 M, [Br2] = 1.9 x 10-3 M, and [NOBr] = 6.9 x 10-3 M, is the reaction at equilibrium? If not, predict the direction in which reaction will occur to reach equilibrium.
(c) What is the รยGo and รยSo of the above reaction? Is the reaction spontaneous or nonspontaneous at 25oC
(d) At what temperature in oC the spontaneity of the above reaction will shift? (i.e. spontaneous becomes non-spontaneous or vice versa)
