which equation is an example of a endothermic reaction. Reactants Heat Energy -- Products A reaction may involve multiple processes and some of these may release heat but as long as a reaction involves a net reduction in temperature the reaction is endothermic. CoCl 2 6H 2 O s 6 SOCl 2 l CoCl 2 s 12 HCl g 6 SO 2 g The release of a large number of moles of gas in this reaction results in a large entropy gain that drives it forward.

A very common example of an endothermic chemical reaction is photosynthesis. Consider the reaction mixturesalt plus wateras the system and the flask as the surrounding. Endothermic reactions are those reactions that require absorbing energy to happen.
A hallmark of this type of reaction is that it feels cold.
The DH is positive for an endothermic reaction. The equation for this reaction is. Since this physical change cannot occur without the heat input from surroundings this phenomenon is classified as an endothermic process. Figure2 In endothermic reactions the temperature of the products is typically lower than the temperature of the reactants.
