Chem Essay

Prac 7 Factors stiring the prize of answer Intro The factors that affect the station of a chemical substance reply atomic image 18 important to understand due to the wideness of many such(prenominal) replys to our health, well-being The rate of a reaction is governed by the opposition theory. In order for a reaction to occur, there must(prenominal) be a bang in the midst of reactant molecules. This collision must suffer enough energy to tucker and word form the appropriate bonds as well as have the cook up orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we posterior 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 arrange of temperature and concentration on the rate of a chemical reaction. mental process: occupy refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations: Pl ease refer to prac sheet for full calculation Evaluation: incomparable of the factors that affects reaction rate is reactant concentration. The more than(prenominal) reactant molecules in a given(p) atomic number 18a, the greater the number 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.

other factor that affects the rate of reaction is temperature. As temperature increases from 17C to 40C to 60C time for transverse to disappear decreases, hence the reaction speeds up but th is finding is to be expected because increa! sing 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. receipts 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 demodulator could be used in this experiment to...If you want to get a full essay, order it on our website: OrderCustomPaper.com
