Set up the rate expressions for the following reaction mechanism: A 2 B B +C 3 D If the concentration of B is small compared with the concentrations of A, C, and D, the steady-state approximation may be used to derive the rate law of the overall reaction. 1. Show that this reaction may follow the first-order reaction with [A] at high concentrations (or excess) of [C] kith k3>> k2. 2. Under this high concentrations (or excess) of [C] with k3 >> k2, graph the concentrations of [A], [B], and [D] vs time. Assume the initially only A and C exist in the system.

Question
Set up the rate expressions for the following reaction mechanism:
k
A 2 B
B + C D
If the concentration of B is small compared with the concentrations of A, C, and D, the steady-state approximation may be used to
derive the rate law of the overall reaction.
1. Show that this reaction may follow the first-order reaction with [A] at high concentrations (or excess) of [C] ith k3 >> k2.
2. Under this high concentrations (or excess) of [C] with k3 >> k2, graph the concentrations of [A], [B], and [D] vs time. Assume
the initially only A and C exist in the system.
