Magnitude of rate constant
WebThis is a constant which comes from an equation, pV=nRT, which relates the pressure, volume and temperature of a particular number of moles of gas. It turns up in all sorts of unlikely places! Activation energy, EA This is the minimum energy needed for … WebFor a given reaction under particular conditions, the magnitude of the first-order rate constant does not depend on whether a differential rate law or an integrated rate law is used. The differential rate law requires multiple experiments to determine reactant order; the integrated rate law needs only one experiment.
