Question

5 Thiswould shift the equilibrium to the right and increase the fractionof COCl2 that has decomposed.
Thiswould not have any effect on the equilibrium and not affect thefraction of COCl2 that has decomposed.
Thiswould shift the equilibrium to the left and decrease the fractionof COCl2 that has decomposed.

Explanation / Answer

Molar mass 98.916 g/mol [COCl2] = 6.05 g / 98.916 g/mol / 2.00 L = .031       COCl2 CO + Cl2 Initial: .0306 M      0M    0 M C:       -x              + x      +x F:        .0306-x     x         x Kc = 4.6e-3 = [CO][Cl2] / [COCl2] = [(x)(x)] / (.0306-x) x = .0098 answers: [CO] = [Cl2] = .0098 M [COCL2] = .0306-x = .0306 - .0098 = .021 M Part B: amount decomposed: .0098 / .0306 = .32 Part C: If you add more CO: the reactions shifts towards more toCOCl2 (reactions shift to the back/left)
