How to determine which reaction is faster
WebMar 26, 2016 · Sometimes chemists want to speed the slow ones up and slow the fast ones down. There are several factors that affect the speed of a reaction: Nature of the reactants. Particle size of the reactants. Concentration of the reactants. Pressure of gaseous reactants. Temperature. WebFeb 22, 2016 · You can also determine which reaction is fast and which reaction is slow if you are given the rate law. Which ever reactants are present in the rate law are the reactants in the slow reaction. Top Janae Yip 3G Posts: 15 Joined: Fri Sep 25, 2015 10:00 am Re: Determining slow v fast reaction?

How to determine which reaction is faster
Did you know?
WebThe Effect of the Leaving Group in S N 2 Reactions. The key principle here is that the better the leaving group, the faster the S N 2 reaction. And this is true for any substitution and elimination reaction because the easier it is for the nucleophile to kick out the leaving group, the faster this replacement will occur. WebThe slow step of a reaction is known as the rate determining step. As long as there is a lot of difference between the rates of the various steps, when you measure the rate of a reaction, you are actually measuring the rate of the rate determining step. Reaction mechanisms and orders of reaction

WebUsing the results of experiments like these, the average rate of the reaction can be calculated. No matter which quantity is measured during the course of a reaction, the …
WebSome chemical reactions are fast; others are slow. Sometimes chemists want to speed the slow ones up and slow the fast ones down. There are several factors that affect the speed … WebMar 1, 2016 · Re: Determine which reaction is faster. You will have to look at the activation energy, the bigger the "hump", the harder it is to get to the product, the slower the rate (ie, the smaller the rate constant).
