When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an ...
Endothermic reaction : The reaction in which heat is absorbed is called an endothermic reaction. When KNO(3(S)) dissolves in water, there is absorption of heat during the reaction and the termperature of the solution falls. KNO(3(S)) + H(2)O(I) + "
It provides a rough estimate of the average molecular weight of the fat or oil used in saponification. Saponification Applications It's found in fire extinguishers. Burning oils are converted into non-combustible salts that aid in fire extinguishment. Because this reaction is endothermic, it lowe...
