Before carrying out any experiment or demonstration based on this guidance, it is the responsibility of teachers to ensure that they have undertaken a risk c52d explain the effects on rates of reaction of changes in temperature, concentration and pressure in terms of frequency and energy of collision between particles. The rate of reaction between sodium thiosulphate and hydrochloric acid – chemistry iaa although, the anything that is highlighted in yellow is parts of the experiment in which we made it reliable: 1) place a black 7) take the temperature of the liquid at the end of the reaction and record the average 8) empty the. The factors to discuss might be: amount of limestone temperature of reactants acid concentration volume of acid size of limestone pieces(relate to surface area stirring of the reacting mixture size of reaction vessel volume of thiosulphate any. This worksheet asks students several questions around rate of reactions & temperature it includes questions on state symbols, acids, effect of temperature on rate and has pupils draw a graph from results, as well as add a second line to the graph aft. Temperature - heating chemical substances can make the molecules separate and move around faster we will be investigating the rates of reaction when we will mix together sodium thiosulphate and hydrochloric acid in this experiment we did a trial run to familiarise ourselves with the experiment and the equipment. Chemistry practical manual unit 3: practical skills c6: investigate how changing a variable changes the rate of reaction gcse for first teaching from september 2017 in this experiment we will be looking at how quickly magnesium reacts with dilute hydrochloric acid use the same temperature of reaction use the.
