In a reaction , `A + B rarr` Product, rate is doubled when the concentration of `B` is doubled, and rate increases by a factor of `8` when the concentration of both the reactants (A and B) are doubled, rate law for the reaction can be written as

For reaction A + B rarr products, the rate of the reaction was doubled when the concentration of A was doubled. The rate was also doubled when the concentration of both A and B were doubled. Then, order of the reaction with respect to A and B are :

For a reaction 2A rarrB Products , doubling the concentration of B alone doubles the rate and doubling the initial concentration of both the reactants increases the rate by a factor of 8 . The rate law for the reaction is

For the reaction A + 2B to C, the reaction rate is doubled if the concentration of A is doubled , the rate is increased by four times when concentrations of both A and B are increased by four times . The order of the reaction is _______.
