Chemical kinetics‚ also known as reaction kinetics‚ is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction’s mechanism and transition states‚ as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864‚ Peter Waage and Cato Guldberg pioneered the development of chemical kinetics

he terms “chemical accident” or “chemical incident” refer to an event resulting in the release of a substance or substances hazardous to human health and/or the environment in the short or long term. Such events include fires‚ explosions‚ leakages or releases of toxic or hazardous materials that can cause people illness‚ injury‚ disability or death. While chemical accidents may occur whenever toxic materials are stored‚ transported or used‚ the most severe accidents are industrial accidents‚ involving

A Critical Analysis of the Effects of Chemical Castration and Physical Castration on the Recidivism Rates of Sex Offenders Introduction This paper examines the effects of chemical castration and physical castration on the recidivism rates of sex offenders. Using theory integration or the multifactor approach‚ the findings reveal there are several factors influencing sex offender recidivism. Both chemical castration and physical castration have the potential to reduce the recidivism

Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical

DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to
