Problem

Identify the order with respect to the reactant, A. 

(A → product)

i) The half-life of A increases as the initial concentration of A decreases.

 

ii) A two fold increase in the initial concentration of A leads to a four fold increase in the initial rate.

 

iii) A two fold increase in the initial concentration of A leads to a 1.41-fold increase in the initial rate.

 

iv) The time required for [A] to decrease from [A] 0 to [A]0/2 is equal to the time required for [A] to decrease from [A]0/2 to [A]0/4.

 

v) The rate of decrease of [A] is a constant.
