WebKinetics problems Question 1 a) Explain the terms order, overall order, and molecularity as applied to the kinetics of a chemical reaction. b) Outline one method by which the order of a chemical reaction can be determined experimentally. c) The gas phase reaction of fluorine atoms with bromine follows the stoichiometric equation WebHalf-Life Formula. It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1/2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1/2 = 0.693/k.
