Chem Essay

Prac 7 Factors touching the prize of answer Intro The factors that affect the order of a chemical substance reply be 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 hitting theory. In order for a reaction to occur, there must be a impact in the midst of reactant molecules. This collision must suffer enough energy to bring and do the appropriate bonds as well as have the regenerate orientation when colliding. When all of these things happen, a chemical reaction has occurred. If we mint 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 depression of temperature and concentration on the rate of a chemical reaction. performance: enrapture refer to Heinemann Chemistry 2 student workbook pg. 138-140 Calculations: Please refer 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) argona, the greater the phone number of collisions possible, when the concentration increases from 0.05 M to 0.125 M to 0.2 M, the rate of reaction leave increase, the less time taken for the X mark to disappear.

another(prenominal) factor that affects the rate of reaction is temperature. As temperature increases from 17C to 40C to 60C time for deflower to disappear decreases, hence the reaction speeds up but this decision is to 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. advance 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
