Question

The rate of a chemical reaction is expressd as : Rate = K[A]2

[B].

The order of the reaction would be -

A. 2

B. 3

C. 1

D. 0​

Answer 1

Answer:

If Rate Law for a reaction is expressed as r=k[A]  

p

[B]  

q

 

then  

order of reaction with respect to A is 'p'

order of reaction with respect to B is 'q'

overall order of the reaction is 'p+q'.

Hence, for the Rate Law : r=k[Cl
