which of the following represents the expression for `3//4`th life of first order reaction?

A

`k/2.303 log. 4/3`

B

`2.303/k log. 3/4`

C

`2.303/k log. 4`

D

`2.303/k log 3`

Text Solution

Verified by Experts

`t = (k)/(2.303) "log" (a)/(a-x)`
for `(3^(th))/(4)` life put x = `(3a)/(4)` . Then `t_((3)/(4)) = (2.303) /(k) "log" (a)/(a - 3a //4 ) = (2.303)/(k) "log" 4 `.
