For the reaction 
whose half-life is 100 s at 
and 50 s at 
, what will be the half-life at 
?
Text Solution
Verified by ExpertsThe correct answer is:
A
From the data, doubling 
halves 
, characteristic of a second-order reaction (zero order: 
; first order: 
is independent of 
).
So, going from 
to 2.00 M 
makes 
one-fourth: 
25 s .
