Carbonyl bromide decomposes to carbon monoxide and bromine.
COBr2(g) f CO(g) + Br2(g)
Kc is 0.19 at 73 °C. If an initial concentration of 0.63 M COBr2 is allowed to equilibrate, what are the equilibrium concentrations of COBr2, CO, and Br2?
| [COBr2] = 0.11 M, [CO] = 0.26 M, [Br2] = 0.26 M |
| [COBr2] = 0.28 M, [CO] = 0.35 M, [Br2] = 0.35 M |
| [COBr2] = 0.30 M, [CO] = 0.33 M, [Br2] = 0.33 M |
| [COBr2] = 0.37 M, [CO] = 0.26 M, [Br2] = 0.26 M |
| [COBr2] = 0.63 M, [CO] = 0.35 M, [Br2] = 0.35 M |
