Heat of Reaction

Science > Chemistry > Chemical Thermodynamics and Energetics > Heat of Reaction The branch of chemistry which deals with the quantitative study of thermal or heat changes in various chemical reactions is known as thermochemistry. In this article, We shall discuss very important concept of chemistry i.e. heat of reaction. Thermochemical Equation: An equation which […]
