The thermochemistry
WebA general survey is made of the available data for the standard Gibbs energies of formation of solid carbides of transition metals. The results are plotted as standard Gibbs energy vs. temperature diagrams. The equations and the estimated accuracy when available are given for each substance. Download to read the full article text. WebThe Theory. Thermochemistry is the study of heat and energy associated with a chemical reaction or a physical transformation. A reaction may absorb or release energy. The reaction which absorbs energy in the form of heat is called endothermic reaction and that which releases energy in the form of heat is called exothermic reaction.
