The rate of a reaction increases eight times when the concentration of the reactant increases four times. The order of the reaction is

In a reaction A to B, the rate of reaction increases eight times on increasing the concentration of the reactant four times, then order of reaction is:

In a reaction A to B the rate of reaction increases two times on increasing the concentration of the reactant four times, then order of reaction is

In a reaction A to B the rate of reaction increases two times on increasing the concentration of the reactant four times, then order of reaction is

The rate of a reaction increases four-fold when the concentration of reactant is increased 16 times. If the rate of reaction is 4 xx 10^(-6) mol L^(-1) s^(-1) when the concentration of the reactant is 4 xx 10^(-4) mol L^(-1) . The rate constant of the reaction will be
