For a reaction : A + B rarr Products, ...

For a reaction : `A + B rarr` Products,
The rate law expression is, rate `= k[A]^(1//3)[B]^(2)`
What are the units of rate constant, if concentration is measured in mol `dm^(-3)` and time in seconds ?

Text Solution

Verified by Experts

Rate constant , `k = ("rate")/([A]^(1//3)[B]^(2))`
`therefore` Units of rate constant `= ("mol dm"^(-3)s^(-1))/(("mol dm"^(-3))("mol dm"^(-3))^(2))`
`= ("mol dm"^(-3))^(1-7//3) s^(-1) = ("mol dm"^(-3))^(-4//3)s^(-1)`
`= dm^(4) mol^(-4//3)s^(-1)`
