WitrynaEndothermic the exothermic reactions are chemical store that absorb additionally release heat, respectively. AMPERE good example of an endothermic reaction exists photosynthesis. Combustion is an example of an exothermic reaction. Which categorization of a reaction as endo- or exothermal depends on the gain heat shift. WitrynaThe endothermic dissociation process dominates over the exothermic hydrolysis process in one mode and the reverse trend is observed in the other. For both the drugs transition from one mode to the other occurs at about 295K. Dissociation Constants of these drugs have been determined with various concentration and temperature. office 365 ipアドレス url
