Problem
For the reaction 2A+B→products, the rate law is rate=k[A]2[B]. Initial concentrations for three experiments are given.
Experiment | [A] (M) | [B] (M)
1 | 0.10 | 0.10
2 | 0.20 | 0.05
3 | 0.05 | 0.20
Based on the rate law, rank the experiments from fastest to slowest initial rate.
(a) 3>1>2
(b) 1>2>3
(c) 2>1>3
(d) 3>2>1
