Unit of K for third order reaction is

Answer»

`(("litre")/("mole")) sec`
`(("mole")/("litre")) sec`
`(("litre")/("mole"))^(-1) sec^(-1)`
`(("mole")/("litre"))^(-1) sec^(-1) `

SOLUTION :UNIT of rate constant for a `N^(th)` order reaction is `(("LIT")/("mol"))^(n-1) sec^(-1)`
When n = 3 , the unit of rate constant is
`(("lit")/("mol"))^(2) sec^(-1)` or `(("mol")/("lit"))^(-2) sec^(-1)`.
