Expert Answer:
Nitric acid is prepared by reaction of nitre(KNO3) and H2SO4 .
Chemical equation for this process is-
It is a type of displacement reaction, where high reactive K is displacing low reactive H.
When we are using Pb(NO3)2 instead of KNO3 then reaction rate is slow because Pb is very less reactive than K so it will take time to displace H.
So, KNO3 is preferred due to its hiogh reactivity.
