Noun1.endothermic reaction- a chemical reaction accompanied by the absorption of heat chemical reaction,reaction- (chemistry) a process in which one or more substances are changed into others; "there was a chemical reaction of the lime with the ground water" ...
Physical chemistry is studied through models. In a thermodynamic model, the Universe is divided into the System and the Surroundings. The System is the matter or reaction of interest and, the Surrounding is everything apart from that. When we consider an ice cube melting, the ice cube is the...
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) + "

A negative value of an enthalpy change, ΔH < 0, indicates an exothermic reaction (heat given off to the surroundings); a positive value, ΔH > 0, indicates an endothermic reaction (heat absorbed from the surroundings). If the direction of a chemical equation is reversed, the arithmetic ...
There are two types of chemical reaction GCSE chemistry students have to understand: endothermic and exothermic. But what's the difference? The former absorb energy from the surroundings, while the latter release it. Revise what you learned about them in

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 betweencitric acid and baking sodais a highly safeexample of an endothermic reaction, commonly used as a chemistry demonstra...

Photosynthesis is a good example of an endothermic reaction. Combustion is an example of an exothermic reaction. The categorization of a reaction as endothermic or exothermic depends on the net heat transfer. In any given reaction, heat is both absorbed and released. For example, energy must be ...
