Half of a substance ts consumed tn 40 min. When the quantity of substance ts decreased to half, the half-life of the change is 80 min. The order of reaction is...

Text Solution

Verified by Experts

`(t_(1/2)_1/(t_(1/2)_2 = [x/(x/2)]^(1-n) implies (40)/(80) = (2)^(1-n)`
`implies 2^-1 = 2^(1-n) implies n =2`
