When the inner bag of water is broken by squeezing the package, it is allowed to dissolve the solid in an endothermicreaction.

Whereas, in an endothermicreaction, or system, energy is taken from the surroundings in the course of the reaction.

Looking at a plot of an endothermicreaction, it can be determined that as temperature increases, the equilibrium constant also increases.

A negative value indicates that heat is absorbed during the formation of the compound from its elements; such a reaction is called an endothermicreaction.

They are also thought to influence the dynamics of mantle convection in that the exothermic transitions reinforce flow across the phase boundary, whereas the endothermicreaction hampers it.

Case (c) depicts the potential diagram for an endothermicreaction, in which, according to the postulate, the transition state should more closely resemble that of the intermediate or the product.

For the anticipated organisms this means they decompose exothermically at a relatively low temperature compared to the endothermic reactions of the inorganic soil. Factors such as torquing, gross mechanical plastic deformation, fracture and related structural phase changes and diffusion, spalling, endothermic reactions, melting, ablation, and vaporization reduce the effective momentum coupling. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions.

Since the entropy increases with temperature, many endothermic reactions preferably take place at high temperatures.
