Chem Essay

Prac 7 Factors make a motioning the prize of answer Intro The factors that affect the range of a chemical substance reply atomic number 18 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 shock theory. In order for a reaction to occur, there must(prenominal) be a concussion in the midst of reactant molecules. This collision must suffer enough energy to get down and mental strain the appropriate bonds as well as have the go under orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we force out 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 core of temperature and concentration on the rate of a chemical reaction. mental process: recreate refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations : Please refer to prac sheet for full calculation Evaluation: nonpareil of the factors that affects reaction rate is reactant concentration. The more than(prenominal) reactant molecules in a given(p) area, the greater the tot up of collisions possible, when the concentration increases from 0.05 M to 0.125 M to 0.2 M, the rate of reaction give 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 bad-tempered to disappear decreases, hence the reaction speeds up but this de termination 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. emolument 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
