Rates of reaction investigation planning aim:- the aim of this investigation is to find out what factors effect the rate of reaction between magnesium and hydrochloric acid and what kind of effect does one of the factors have on the rate of reaction between the two the factor that i'll be looking. Chemistry coursework rates of reaction investigation introduction in this investigation i am going to be investigating the reaction between marble chips and hydrochloric acid, and to see what differences in the rate of this reaction arise when different concentrations of acid are used. 2 1 introduction chemical reaction kinetics deals with the rates of chemical processes any chemical process may be broken down into a sequence of one or more single-step processes known either as elementary. A correlation of reaction rates according to the leffler analysis and the investigation of the abstraction reactions by h and d from.
A higher concentration of a given substance may cause a reaction to proceed at a faster rate when compared to a reaction with a lower concentration of the same given substance this would be because there would be more acid molecules to collide with the magnesium atoms therefore, an increase in. Students know chemical reactions usually liberate heat or plan and conduct a scientific investigation to test a solve the problems of lesson review.
