In a reaction, if the concentration of the reactant R is quadrupled, the rate of reaction becomes sixty four times. What is the order of reaction?

Text Solution

Verified by Experts

`r_1 = k (R)." "...(i)`
`r_2 = k(4R)." "...(ii)`
On dividing Eq. (ii) by Eq. (i), we get
`(r_2)/(r_1) = (k (4R)^(r ) )/( k(R )^(r) ) = 64 = (4)^(r)`
`rArr (4)^(3) = (4)^(r)`
`rArr " "r=3`
