In contrast, in endothermic reactions, heat is consumed from the environment.
Since the entropy increases with temperature, many endothermic reactions preferably take place at high temperatures.
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.
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.
For the anticipated organisms this means they decompose exothermically at a relatively low temperature compared to the endothermic reactions of the inorganic soil.
Case (c) depicts the potential diagram for an endothermic reaction, in which, according to the postulate, the transition state should more closely resemble that of the intermediate or the product.
They are also thought to influence the dynamics of mantle convection in that the exothermic transitions reinforce flow across the phase boundary, whereas the endothermic reaction hampers it.
T-peak is the position where the endothermic reaction occurs at the maximum.
