Carbonyl bromide, COBr2, decomposes to CO and Br2 with
and equilibrium constant of Kc of 0.190 at 73C.
COBr2(g) <--> CO (g) + Br2 (g)
if 0.015 mol COBr2 is in a 2.50 L flask at equilibrium, what are
the concentrations of CO and Br2 at equilibrium?
ans) COBr2 CO + Br2
given 0.015 /2.5 0 0
= 0.006M 0 0
at eqm conc 0.006 - x x x
Kc = [ CO ] [ Br2 ] / [ COBr2 ]
0.190 = x2 / 0.006 -x
by solving x = 0.03376 M
[ CO ] =X = 0.03376M
[Br2 ] = X = 0.03376M
