If a reaction is endothermic, where heat is absorbed as the reaction progresses from reactants to products, then increasing the temperature will increase the equilibrium constant. The opposite is true if a reaction is exothermic.

WebDec 10, 2024 · Dissolution can be both exothermic like for $\ce{NaOH}$ or $\ce{H2SO4}$, or endothermic like for $\ce{CaCl2 . 6 H2O}$, $\ce{KNO3}$ or $\ce{KClO3}$.. The net thermal effect sign is determined by combination of endothermic breaking of a ionic lattice or chemical bonds and of exothermic ion hydration. WebEndothermic animals generate heat through metabolic processes such as digestion and muscle contraction. They also have the ability to shiver, which increases muscle activity and heat production. In contrast, exothermic organisms, also known as cold-blooded animals, do not have the ability to regulate their body temperature internally.

WebJun 22, 2024 · Cooking food is endothermic because food receives heat energy during cooking. It doesn’t release energy while cooking. The heat is distributed through the food while it is cooking, and that is why we get our food prepared. The heat is basically making the food to be cooked. It’s clear that the food absorbs the heat while cooking. today in history google searchWebMar 14, 2024 · A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings.
