Answer properly (show complete solution) and elaborate.

Carbonyl bromide decomposes to carbon monoxide
and bromine.
COBR,(g) 2 CO(g)
K, is 0.190 at 73 °C. Suppose you place 0.500 mol of
COB1, in a 2.00-L flask and heat it to 73 °C (see Study
Question 17). After equilibrium has been achieved, you
add an additional 2.00 mol of CO.
(a) How is the equilibrium mixture affected by adding
more CO?
(b) When equilibrium is reestablished, what are the new
equilibrium concentrations of COBR2, CO, and Br2?
(c) How has the addition of CO affected the percentage
of COBR2 that decomposed?
