Answer:
<u>In this reaction heat is released</u>
Explanation:
Exothemic Reactions : Those reactions in which heat is released when the products are formed .
For such reaction The enthalpy change is negative.
for exothermic reaction
Endothermic Reactions : Those reaction which proceed by absorbing heat . Here heat is absorbed. The enthalpy change for such reactions is positive.
When the direction of reaction reverses , the value of H also changes.
In the given reaction,

= heat is absorbed
So,

= heat is<u> released</u>
<u></u>
<u>E</u><em>xothermic reactions are more spontaneous as compared to endothermic ractions. This means that they proceed own their own . Only little amount of energy is supplied to exothermic reaction to produce the prodct.</em>
