What is the order of reaction whose rate constant has the same

. Second order 

The answer is.... Zero order

r = k(a)n => 2r = k(4a)n =>2 = 4n => n = 0.5

Order of reaction = ½ + 2 = 2.5

your the answer t = 444 seconds

No, an elementary process would have a rate law with orders equal to its molecularities and therefore must be in integral form.

Second order

First order reaction.

t = 444 seconds

An experimentally determined expression which relates the rate of reaction with the concentration of reactants is called rate law while the rate of reaction when concentration of each reactant is...
