Question

write the unit of velocity constant for first, second and third order reaction​

Answer 1

Answer:For second order reaction, rate=k[A] 2

rate=k[A][B]

M/s =k×(M)

2

k=/M/s

The unit of velocity constant for second order reaction is k=/M/s or k=M −1 s −1

Explanation:

Answer 2

Answer:

For first order reaction, rate constant,

k= 2.303/t log(Ro/R)

The unit of rate constant for first order,second order or third order reaction is:

unit of K=Molarity/time

= M/s
