Web24 Jan 2024 · Observation skills are at the core of practical work and these skills are developed as students progress through a range of experiments. Some of the difficulties encountered in making observations were discussed in an earlier article.In rate experiments, students need to make a judgement about the ‘end point’ when timing a reaction. Web24 Aug 2024 · 14.1: Factors that Affect Reaction Rates. chemical kinetics – area of chemistry dealing with speeds/rates of reactions. rates of reactions affected by four factors. concentrations of reactants. temperature at which reaction occurs. presence of a catalyst. surface area of solid or liquid reactants and/or catalysts.
WebThe understanding of rates of reaction is a key step towards assessment of the feasibility of a reaction. The branch of chemistry which deals with this understanding is called chemical kinetics. The rate of a chemical reaction is defined in terms of the change in concentration of a designated chemical species which is a part of the given reaction.
