Suppose that we have three chemical species, A, B and C, where A is converted to B, and B is converted to C. Suppose Remember that square brackets denote a concentration. Thus, for example, [B] is the concentration of B.

further that [B] = a[A] +

b, and that [C] =

[B]

2 K2 C

+[B]

, where a, b and KC are constants.

a. How does [C] depend on [A]?

b. What are the possible values for a and b? (For example, are they always negative, always positive, or could they be either?)

c. If the concentrations of A, B and C are given in M, what are the units of

a, b and KC?
