An endergonic and endothermic reaction occurs when energy is absorbed from the surroundings. In endothermic reactions, heat is absorbed. If you mix sodium carbonate (baking soda) and citric acid in water, the liquid becomes cold, but not cold enough to cause frostbite. ...
Energy can be released or absorbed in many forms, including light, electricity and heat. When energy is released as heat, the process is exothermic, and when heat is absorbed, the process is endothermic. An endothermic reaction is one which results in a net decrease in temperature because it...
An endergonic reaction is a reaction in which the net change in free energy is positive, and energy is absorbed during the reaction. The change in the standard Gibbs free energy (G) for an endergonic reaction is positive. Answer and Explanation: ...
A. endothermic B. exothermic C. isothermal D. adiabatic 相关知识点: 试题来源: 解析 B。本题考查化学反应的类型。A 选项 endothermic 是吸热的。B 选项 exothermic 是放热的,符合题意。C 选项 isothermal 是等温的。D 选项 adiabatic 是绝热的。反馈...
I don't get how ionization is an endothermic reaction. In an endothermic Reactions: the reactants have less potential energy than do the products. Energy must be input in order to raise the particles up to the higher energy level.
A. to the left B. to the right C. not at all D. randomly 相关知识点: 试题来源: 解析 B。原因:If the forward reaction is endothermic (absorbs heat), then increasing the temperature will shift the equilibrium to the right.反馈 收藏 ...
