Question

Reaction is first order in a and second order in b write the differential rate equation

Answer 1

Answer:

Given that

Order of reactant A, x = 1

Order of reactant B, y = 2

The differential rate equation will be

Plug the value in this formula

Given that concentration of B is increased three times

So that

New concentration of B = 3[B]

Plug the values we get new rate of reaction

Hence, the rate of reaction will increase by 9 times.

(iii)

Given that

New concentrations of A = 2[A]

New concentration of B = 2[B]

Plug the values we get

Hence the rate of reaction increased by 8 times
