Stephanie chun march 5, 2010 2213-020 internal assessment – investigating the relationship between concentration of reactants and rate of reaction using hydrochloric acid and magnesium strip. 502 kinetics of the persulfate-iodide clock reaction (4 points) in this experiment you will investigate the kinetics of the reaction between persulfate and iodide ions s 2o 8 2-+ 2i-→ 2so 4 2-+ i 2 (r1) the rate of reaction may be measured by adding a small, known quantity of thiosulfate. Graph 1 shows the relationship between change in temperature and the rate of reaction the trend shows that the as the temperature of the hcl increases, so does the rate of reaction this is a polynomial relationship, which implies that the rate of reaction increases exponentially in relation to the increase in temperature.
Kinetics study on the reaction between sodium thiosulphate and hydrochloric acid - meity olabs - duration: rates of reaction graphs and orders - duration: 8:20 allery chemistry 31,165 views. The relationship between the concentration of a reactant and the rate of the effect of concentration on rate: assessing learning 1 label the following equation as fully as you can r a = k[a] a[b]b models for explaining rates of reactions. Therefore the rate of the reaction between na 2 s 2 o 3 and hcl is directly proportional to the concentration of na 2 s 2 o 3 solution learning outcomes students understand the effect of concentration of the reactant on the rate of a chemical reaction.
Introduction the purpose of this lab is to observe the effect of concentration on reaction rates, to ultimately determine the rate law for the reaction between the iodide ion (i-) and the persulphate ion (s 2o8 2-.
