Reaction is of zero order as the unit of rate constant is mol L⁻¹ S⁻¹
.·. Concentration of B =k × t =0.6×10⁻³ × 20 × 60 = 0.72 M
Let at time t=0 (A)= a and (B)=0
At time t=(20*60)sec (A)= (a-x) and (B)=x then
For 1st order reaction
(A’) =(A) – kt
: a-x = a – 0.6*10-3*20*60
Solving it will give
X= 0.72 M
