The following results were obtained when the reaction represented above was studied at 25°C: A + 2B -> C + D
_
a) Determine the order of the reaction with respect to A and B.
b) Write the rate law for the reaction.
c) Calculate the value of the rate constant, k, specifying units.
d) Determine the initial rate of disappearance of substance B in Experiment 2.
_
e) Identify which of the reaction mechanisms represented below is consistent with the rate law developed in part B. Justify your choice by writing rate laws for each mechanism. Also, identify any intermediate(s) and/or catalyst(s) in your chosen mechanism. (6 pts - 1 pt for chosen mechanism, 1 pt for each rate law, 2 pts for intermediate(s)/catalyst(s))
_
Mechanism #1: A -> M (slow)
M + B -> C + X (fast)
X + B -> D (fast)

Mechanism #2: B ⇋ M (fast equilibrium)
M + A -> C + X (slow)
B + X -> D (fast)

Mechanism #3: A + B ⇋ M (fast equilibrium)
M + B -> C + X (slow)
X -> D (fast)
