WebNow the last clue is the slope of your line. When you figure out what the order is, the slope would equal negative of your k. So negative of your rate constant if it's a zero order reaction. If it's a first order reaction, your slope is also equal to -k. So negative of your rate constant. Then if it's the second order reaction, the slope of ... WebThe exponents of the reactant concentrations x and y are referred to as partial orders of the reaction. Therefore, the sum of all the partial orders of the reaction yields the overall order of the reaction. How to Determine …
