The equilibrium constant for the reaction BrCl(g) 1/2 Br2(g) + 1/2 Cl2(g) is Keq

Question

The equilibrium constant for the reaction

BrCl(g) 1/2 Br2(g) + 1/2 Cl2(g)


is Keq = 1.23e+00 at 1936 K. Calculate Keq for the reaction 1/2 Br2(g) + 1/2 Cl2(g) BrCl(g) at this temperature and figure out whether the equilibrium favors Br2 and Cl2 or BrCl at this temperature. Pick the correct choice from below.



a) Keq = 1.11e+00; At this temperature the reaction favors BrCl.
b) Keq = 9.03e-01; At this temperature the reaction favors Br2 and Cl2.
c) Keq = 8.15e-01; At this temperature the reaction favors Br2 and Cl2.
d) Keq = 1.51e+00; At this temperature the reaction favors BrCl.
e) Keq = 6.64e-01; At this temperature the reaction favors BrCl.

Explanation / Answer

c) Keq = 8.15e-01; At this temperature the reaction favors Br2 and Cl2.
