Question

For the reaction A  B, the rate of reaction becomes three times when the
concentration of A is increased by nine times. What is the order of reaction ?

Answer 1

Answer:

order of reaction= 2

Explanation:

rate r = k[A]^n

now 9r = k[ 3A]^n

hence

(r/9r) = (A/3A)^n

so, n=2

where n = order of reaction
