WebChemical reactions that release energy are called exothermic reactions. Some chemical reactions absorb energy and are called endothermic reactions. You will study one exothermic and one endothermic reaction in this experiment. In Part I, you will study the reaction between citric acid solution and baking soda. An equation for the reaction is: … WebEnergy diagrams for endothermic and exothermic reactions. In the case of an endothermic reaction, the reactants are at a lower energy level compared to the products—as shown in the energy diagram below. In other words, the products are less stable than the reactants.

WebSep 7, 2016 · Endothermic reaction absorbs heat and an exothermic reaction releases heat. After Jonas mixes citric acid with baking soda, heat is required to start the reaction. Therefore it is an endothermic reaction and not an exothermic one. Endothermic reactions do not start spontaneously they need heat to start the reaction. WebMay 9, 2024 · In both processes, heat is absorbed from the environment. You could record the temperature change using a thermometer or by feeling the reaction with your hand. The reaction between citric acid and baking soda is a highly safe example of an endothermic reaction, commonly used as a chemistry demonstration. WebJan 21, 2015 · In endothermic reactions heat energy is removed by the reaction (“taken in”) and the temperature of the reactants decreases. Below are two chemical reactions that use household products. Find out whether they are exothermic or endothermic. ...
