For a given reaction $R \to P,{t_{1/2}}$ is related to ${[A]_0}$ as given in table.
Given: $\log 2 = 0.30$
Which of the following is true?
A. The order of the reaction is 1/2.
B. If ${[A]_0}$ is 1 M , then ${t_{1/2}}$ is $200\sqrt {10} \;{\rm{min}}$
C. The order of the reaction changes to 1 if the concentration of reactant changes from 0.100 M to 0.500 M.
D. ${t_{1/2}}$ is 800 min for ${[{\rm{A}}]_0} = 1.6{\rm{M}}$
