Question

the quantity of heat evolved or absorbed during a Chemical reaction is called
1) heat or reaction
2) heat of formation
3) heat of combination ​

Answer 1

Answer:

heat of reaction

Explanation:

heat of reaction

Answer 2

The quantity of heat evolved or absorbed during a Chemical reaction is called heat of reaction. (Option 1)

Heat of reaction

• When the number of moles of reactants specified by the chemical equation has completely reacted, the heat of reaction is the amount of heat emitted or absorbed.
• The enthalpy change, also known as the heat of reaction, is the amount of heat energy given out or absorbed in during a chemical process.
• H is the symbol for this. In most cases, the heat of the reaction is measured in kilojoules. The heat of the reaction might be positive or negative.
• H is negative in exothermic processes. H is positive in endothermic processes. Because the heat of combustion data could be estimated directly or indirectly, the heat of a reaction could be determined.
