Yes, during the time it absorbs energy to break bonds.
Yes, energy is consumed during the initiation of an exothermic reaction to break bonds in reactant molecules. Once the reaction starts, it releases more energy than it consumes, resulting in a net release of energy overall.
During an exothermic reaction.
NO
A reaction that releases energy is exothermic.
Energy is only transformed from one form to another. In exothermic reaction the energy within the bonds is transformed into energy released as heat
In an exothermic reaction the energy of the products is less than that of the reactants.
Exothermic reactions
Exothermic reaction is a reaction which gives out heat. For example: when natural gas burns it release its energy to the surroundings which could be the water in a central heating system. this is a EXOTHERMIC REACTION between natural gas and oxygen.
An exothermic reaction releases energy to its surroundings.
You can determine if a chemical reaction is exothermic by measuring the temperature change of the surroundings. If the temperature increases during the reaction, then it is exothermic. Additionally, you can look for the release of heat or light during the reaction as indicators of an exothermic process.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
When energy is released during a reaction, it is considered an exothermic reaction. This means that the reaction is giving off heat to the surroundings.
