Rate constant of a reaction (k) is 175 "...

Rate constant of a reaction `(k)` is `175 "litre"^(2) "mol"^(-2)sec^(-1)`. What is the order of reaction ?

A

First

B

Second

C

Third

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
C
For a 3rd order reaction
`k = ("rate")/("Conc")^(3)`
Unit of `k=("mol L"^(-1)"s"^(-1))/(("mol L"^(-1))^(3))="mol"^(-2)"L"^(2)"s"^(-1)` .
