For the reaction `2" X"to"X"_(2)`, the rate reaction becomes 27 times when the concentration of X is increased three times. What is the order of the reaction ?

Text Solution

Verified by Experts

The correct Answer is:
3
(i) `r=k[X]^(n),"(ii) "27r=k[3" X"]^(n)" Dividing (ii) by (i),"27=3^(n)" or "3^(3)=3^(n)" or "n=3`
