At 4 minutes [A] is increased to 0.8 M. Equilibrium is
re-established at 6 minutes. Show on the graph how
[A] changes between 4 and 10 minutes. (Don't
worry about the exact concentrations at equilibrium
- just show general trends and relative amounts).

If the equilibrium constant for A (blue) B (red) is K
of A and B
< 1, what are the relative concentrations
at equilibrium? (Hint: look at your graph)
A) [A] > [B]
B
[A] < [B]
