APFIVE Effect of Concentration on Reaction Rate
The rate law for a reaction is given by $$Rate = k[A]^{1.5}$$. If the concentration of reactant A is increased from 0.2 M to 0.4 M, by what approximate factor will the reaction rate increase?
A
Approximately 2.83
B
4.0
C
Approximately 3.16, which might be derived from incorrectly assuming a simple doubling without accounting for the 1.5 order dependence.
D
2.0
