Definition: In this task, you are given a multiple-choice question about healthcare. Answer the question based on your information and classify your answers into '1', '2', '3', and '4'.
Input: Question: The equation of speed of a chemical reaction: 
 Options:  <1> It must be determined from kinetic measurements and can not be deduced directly from the stoichiometry of the reaction. <2> Allows the units of s-1 (s = second) to be assigned to the velocity constant. <3> It depends on the total reaction order that, in turn, is obtained from the stoichiometric coefficients of the products. <4> Report in detail about the reaction mechanism. <5> It depends on the experimental conditions of the process.
