In a reaction, the initial conc. of the reactants increases four fold and rate becomes eight times of its initial value, order of reactions is

Answer:

Solution:

Let the rate law be

$r = k {(c)}^{n} ... (i)$

on increasing concentration

$8 r = k {(4 c)}^{n}$ ... (ii)

$2^{3} = 2^{2 n}$

$2 n = 3$

$n = 1.5$
