Define order of a reaction? Give example of fractional order reac-tion? `NO_2+H_2rarrN_2+H_2O` If the conc of `NO_2` is doubled the reaction rate becomes 4 times as compare to initial rate and if `H_2` of doubled the rate become doubled as compare to the initial rate find the overall order of the reaction.
