14.2: Measuring Reaction Rates - Chemistry LibreTexts
网页2023年7月12日 · Initial Rate of Reaction. The initial rate of reaction is the rate at which the reagents are first brought together. Like the instantaneous rate mentioned above, the initial rate can be obtained either experimentally or graphically.
6.2: Enzyme kinetics - Biology LibreTexts
网页The general approach is to add a known concentration of substrate to the enzyme and to determine the initial reaction rate for that concentration of substrate. Reaction rates are typically given as moles (or micromole) of product produced per unit of time (sec or min) per mole (or micromole) of enzyme.
The Method of Initial Rates (Experiment) - Chemistry LibreTexts
网页2021年9月22日 · The rate law of a chemical reaction is a mathematical equation that describes how the reaction rate depends upon the concentration of each reactant. Two methods are commonly used in the experimental determination of the rate law: the method of initial rates and the graphical method.
First-order reactions (video) | Kinetics | Khan Academy
网页The integrated rate law for the first-order reaction A → products is ln[A]_t = -kt + ln[A]_0. Because this equation has the form y = mx + b, a plot of the natural log of [A] as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k.
2.3: First-Order Reactions - Chemistry LibreTexts
网页2023年2月13日 · A first-order reaction is a reaction that proceeds at a rate that depends linearly on only one reactant concentration.
Chemical Kinetics: Method of Initial Rates - Davidson College
网页The initial rate, r0, is the rate of reaction at time t = 0. In the Method of Initial Rates, the differential rate law is determined by varying the initial concentrations of the various reactants and observing the effect on the initial rate. One challenge in this method is to accurately determine the initial rate.
