What are Exothermic Reactions? (with Examples and Video)

WebDec 13, 2024 · Exothermic reactions have a lower activation energy than endothermic reactions, so the activation energy on the exothermic energy diagram is lower than on the endothermic energy diagram. The transition state or activated complex is a high-energy unstable structure. Bonds breaking and/or forming occur at the same time in this high … WebThe way that the refrigerant causes the lowering of the temperature of the surroundings is by transforming, or changing phase, from a liquid to a gas. This is a heat absorbing or endothermic process. You see, a change of phase from liquid to gas requires the absorption of heat energy from the surroundings. how many five digit zip codes can be formed
