Chem Essay

Prac 7 Factors shanghaiing the prize of answer Intro The factors that affect the post of a chemical substance reply argon important to understand due to the wideness of many such replys to our health, well-being The rate of a reaction is governed by the bang theory. In order for a reaction to occur, there mustiness be a smash in the midst of reactant molecules. This collision must suffer enough energy to rule and manakin the appropriate bonds as well as have the refine orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we corporation subjoin the amount of these favourable collisions, then we increase the rate of the reaction.(1) and comfort. Purpose/Objective: The aim of this lab is to lionise the accomplishment of temperature and concentration on the rate of a chemical reaction. routine: gratify refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations: Please refer to prac sheet for full ca lculation Evaluation: unrivaled of the factors that affects reaction rate is reactant concentration. The more(prenominal) reactant molecules in a given(p) bea, the greater the recite of collisions possible, when the concentration increases from 0.05 M to 0.125 M to 0.2 M, the rate of reaction allow increase, the less time taken for the X mark to disappear.

some other factor that affects the rate of reaction is temperature. As temperature increases from 17C to 40C to 60C time for bilk to disappear decreases, hence the reaction speeds up but this decision is to be expected because increasing temperatu re of resoluteness means reactants are movi! ng faster .they collide more frequently and with more energy. They have more chance of overcoming energizing energy and reacting. rise and Limitation: There were some problems when we were doing this investigate and these errors have produced a minor uncertainty in our prove. * It was grueling to observe when the O mark completely cannot be seen. A light sensing element could be used in this experiment to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
