If `t_(1//2)"vs"(1)/(a^(2))` is a straight line graph then determine the order of reaction -

A

zero order

B

first order

C

second order

D

third order

Text Solution

Verified by Experts

The correct Answer is:
D
For a `n^("th")` order reaction.
`t_(1//2)prop(1)/([a]^(n-1))`[where , n = order of reaction]
`t_(1//2)prop(1)/([a]^(3-1))[becausen=3]`
`t_(1//2)prop(1)/([a]^(2))`
