A (aq) 
B (aq) + C (aq) is a first order reaction.
Time t 
Moles of reagent n1 n2
Reaction progress is measure with the help of titration of reagent ‘R’.If all A, B and C reacted with reagent and have ‘n’ factors 
in the ratio of 1 : 2 : 3 with the reagent.The k in terms of t, n1 and n2 is :
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
A (aq) 
B (aq) + C (aq)
t=0 a 0 0
t=t a–x x x
t= 0 a a
(a – x) + 2x + 3x 
n1
a + 4x 
n1.....(i)
2a + 3a 
n2
.....(ii)
