For a reaction R=> P, the rate becomes 2 times when the concentration of the reactant A is increased 4 times. What is the order of reaction ?
r = k(a)n => 2r = k(4a)n =>2 = 4n => n = 0.5

The rate law for a reaction is Rate = K [A] [B]3/2 Can the reaction be an elementary process ? Explain.
No, an elementary process would have a rate law with orders equal to its molecularities and therefore must be in integral form.

For the reaction A + 2B → C, rate is given by R = [A] [B]^2 then the order of the reaction is
(a) : Order is the sum of the power of the concentrations terms in rate law expression. R = [A] × [B]2 Thus, order of reaction = 1 + 2 = 3.

What do you understand by the rate law and rate constant of a reaction? Identify the order of a reaction if the units of its rate constant are:
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...
