Heat energy may be lost during this process in an exothermic reaction, or it may be absorbed in an endothermic reaction. Each of the types of reactions involves an overall energy change as well as the rearrangement of atoms/molecules. The rearrangement creates the products of the reaction. The...
A chemical reaction is exothermic when: A. 质容质容The products have more energy than the reactants质容质容 B. 联反方放话实支米走平情果联反方放话实支米走平情果The reactants have more energy than the products联反方放话实支米走平情果联反方放话实支米走平情果 C. 象支而习安装火七称...
Exothermic chemical reactionHenry Groombridge WalterPage Ronald
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...

放热反应 exothermic reaction 放热反应中温度过高时逆反应发生, C+D->A+B (吸热反应)。如下面右图,当温度高于红色虚线时,逆反应(吸热反应)有利,薄膜生长的net reaction rate 下降。 如果使用的前驱体 A和B 发生放热反应,CVD 采用Hot wall type。Tube 的温度比基板高, 逆反应主要在tube表面进行,基板主要进行正...
And then it asked me to tell whether this reaction is endothermic or exothermic: H2+ Cl2---> 2 HCl I know that the bond enthalpy is calculated as Hreagents- Hproducts, but I'm still confused. Isn't the bond enthalpy the energy needed to break the bonds between the ions? Then how ...
It reveals the degree of the exothermic (or endothermic) reaction, which is useful for safe handling and processing of those substances. It's also used to properly size relief devices for reactive mixtures. There's lots of published data showing such reactivity testing results. Often though, ...
