Question

for a reaction: A+B➡C,when the initial concentration is doubled, the rate of reaction quadrupled and when the initial concentration of B is doubled there is no charge in the rate of the reaction.
what is the order of reaction with A?
what is the order of reaction with B?

Answer 1

when the initial concentration is doubled, the rate of reaction quadrupled

rate = K[A]^n

In second order reaction initial concentration is doubled . The rate od reaction is quadrupled.

Rate = K[2A]^2

           = 4K[A]^2

So it is seond order

The order of A is second order

In zero order reaction when concentration is change but no change the rate of reaction

Rate = K[B]^0

rate   = K[2B]^0

Rate = K[B]^0

The oder of B is zero
