XY
+ heat
X
+ Y
(g)
(g)
(g)
If initially, at equilibrium, the [XY] = 3.0 M, the [X] = 5.0 M and the [Y] = 6.0 M, draw
a graph similar to the one in question 16 showing qualitatively what happens to the
concentrations of each species as the following changes are made to the system:
Time I - The temperature is increased.
Time II - Some X(
is added to the system
g)
Time III - Some Y
is removed from the system
(g)
Time IV - The temperature is decreased.
