Question

Energy is absorbed or evolved in the form of heat or light during the format of a compound... explain​

Answer 1

during the reaction energy is evolved to produce

the compound. if the heat is supply to the

reactants, it breaks more bonds and speed up

the reaction. energy is used to colloid or produce the particles or molecules

Q/ Energy is absorbed or evolved in the form of heat or light during the format of a compound...Explain!

Ans- Yes, it is because most of the or even all the chemical reactions needs a external agent which will force to undergo a chemical reaction to synthesize/ to displace/ to break down or to Neutralize. All these reactions are Chemical reactions. These chemical reactions takes place when bonds break or form new bonds. Therefore Heat helps in the breaking of bond or formation of new bond.

Other external agents like Electricity, light also helps in the occuring of an Chemical Reactions.

♠️ On the basis of Absorption or release of Energy, the chemical reactions are classified into two groups:-

• Endothermic Reaction:-

The chemical reaction that are accompanied by the intake or the absorption of heat are known as Endothermic reaction. For example:

1. $\large{ \rm{CaCo3 \: \: \normalsize{ \red{\underrightarrow{heat \: energy}}} \: \: \: \large{Cao + Co2}}}$

• Exothermic Reaction:-

The chemical reaction accompanied by the release of energy is also known as Exothermic reaction. For Example:

1. $\large{ \rm{2Mg + O2 \: \: \normalsize{ \red{ \longrightarrow}} \: \: \large{2MgO + \red{heat \: energy \: \uparrow}}}}$
