The half-life periof of the reaction in the above question is

If the initial concentration of reactant in certain reaction is double, the half-life periof of the reaction doubles, the order of a reaction is

Define half life period of a reaction.

The half-life periofs of a reaction at initial concentration 0.1 mol L^(-1) and 0.5 mol L^(-1) are 200s and 40 s , respectively. The order of the reaction is
