With over 20 years of trust in our products, the international boating community knows that when it comes to a mount for electronics, they choose ‘a scanstrut. The temperature of the reaction mixture the concentration of the sodium thiosulphate the concentration of hydrochloric acid changing the pressure in this particular investigation i am going to find out how heat affects the rate of reaction in the reaction of sodium thiosulphate with hydrochloric acid. Catalyst adding a catalyst will speed up a reaction by decreasing the energy needed to break the bonds a catalyst is not chemically consumed by the reaction so does not have an effect on the final products pressure pressure results in there being more particles of each reagent in a smaller area, resulting in more reactions. The units for rate are usually cm 3 s-1 or cm 3 min-1 two ways to measure the volume of a gas produced in a reaction graphs the rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time the graph shows this for two reactions the steeper the line, the greater the rate of reaction. ( may depend on the consistency of your results) for the hydrochloric acid - sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1/time versus a concentration or temperature (1/time = relative rate of reaction.
