In a first order reaction, A to B, if k ...

In a first order reaction, `A to B`, if `k` is rate constant and the initial concentration of the reactant A is 0.5 M, then half-life is

A

`(log 2)/( k)`

B

`("In" 2)/( k)`

C

`(log 2)/( k sqrt(0.5) )`

D

`(0.693)/( 0.5k)`

Text Solution

Verified by Experts

(b) `k = (2.303)/( t_(1//2)) log 2`
or, `t_(1//2) = (2.303 log 2)/( k) = ("In" 2)/( k) ("In" 2 = 2.303 log 2)`
