Does The Rate Constant Have The Same Units As The Rate Oct 27 2022 nbsp 0183 32 Determine the numerical value of the rate constant k with appropriate units The units for the rate of a reaction are mol L s The units for k are whatever is needed so that
You can use the Arrhenius equation to show the effect of a change of temperature on the rate constant and therefore on the rate of the reaction If the rate constant doubles for example To get started look at the rate law formula and understand how the units of the rate constant change depending on the order of the reaction indicated by and NO NEVER

No the rate constant k and the rate of a reaction do not have the same units The rate of a reaction is typically expressed in units of concentration per unit time such as M s moles per The rate constant has units of reciprocal seconds s 1 because the reaction rate is defined in units of concentration per unit time M s The units of a rate constant depend on the rate law
8 The units of k the rate constant depend on the overall order of a reaction For what overall reaction order does the rate constant have the same units as the reaction rate 2 marks 9 The units for a rate constant will vary as appropriate to accommodate the overall order of the reaction remembering that rate is always reported as
