Question

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?
A. `r_(1)=r_(2)=r_(3)`
B. `r_(1)gt r_(2) gtr_(3)`
C. `r_(1)lt r_(2)lt r_(3)`
D. All of these

Answer 1

Correct Answer - c
`r_(1)=K[A]^(1)`
`r_(2)=K[A]^(2)`
`r_(3)=K[A]^(3)`
If `[A] gt 1`,
`r_(3) gt r_(2) gt r_(1)`
