The rate constant in numerically the same for the theee reaction of first, second, and third order. Which reaction should be the fastest and it this true for all ranges of concentrations?

Explanation

`A rarr` Product
`r_(1) = k[A]` for first order
`{:(r_(1)= k[A],,,"for first order" ,),(r_(2)=k[A]^(2),,,"for second order",),(r_(3)=k[A]^(3),,,"for third order",):}`
`k` is same in all.
`If `[A] = 1`, r_(1) = r_(2) = r_(3)`
If `[A] lt 1`, `r_(1) gt r_(2) gt r_(3)`
If `[A] gt 1`, `r_(3) gt r_(2) gt r_(1)`
