Question

the half life becomes 1/4 as initial conc. of reactant doubled.wht is order of reaction​

Answer 1

For third order reaction , n= 3 where nis overall order.
Now half life = 1/(initial conc )^ (n-1)
Half life = 1/(initial conc)^2
LHS = half life
= 1/4

RHS = 1/(initial conc)^2
= 1/(2)^2
= 1/4

Thus , LHS=RHS
So, the order of reaction is 3.
