Chem Essay

Prac 7 Factors considering the prize of answer Intro The factors that affect the account of a chemical substance reply ar important to understand due to the wideness of many much(prenominal) replys to our health, well-being The rate of a reaction is governed by the smasher theory. In order for a reaction to occur, there essential be a bang in the midst of reactant molecules. This collision must suffer enough energy to gravel and course of instruction the appropriate bonds as well as have the line up orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we burn 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 raise of temperature and concentration on the rate of a chemical reaction. surgical procedure: beguile refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations: Please refe r to prac sheet for full calculation Evaluation: one and only(prenominal) of the factors that affects reaction rate is reactant concentration. The more(prenominal) reactant molecules in a given(p) ara, the greater the get along of collisions possible, when the concentration increases from 0.05 M to 0.125 M to 0.2 M, the rate of reaction exit increase, the less time taken for the X mark to disappear.

other factor that affects the rate of reaction is temperature. As temperature increases from 17C to 40C to 60C time for overfly to disappear decreases, hence the reaction speeds up but this finding is t o be expected because increasing temperature! of resoluteness means reactants are moving faster .they collide more frequently and with more energy. They have more chance of overcoming energizing energy and reacting. utility 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 sensor could be used in this experiment to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
