Solution

The correct option is A 0
In an exothermic reaction, the total enthalpy of products is smaller than that of reactants.
Exothermic reactions are the chemical reactions which proceed with the evolution of heat energy.
Consider the reaction $A + B \to C + D + q$ .
Here, q is the heat energy released during this exothermic reaction.
The enthalpy change for this reaction is $Δ H_{r x n} = H_{p r o d u c t s} - H_{r e a c t a n t s} = - q$
Negative sign indicates that heat is released in the reaction.
Hence, $H_{r e a c t a n t s} = H_{p r o d u c t s} + q$
Thus, in an exothermic reaction, the total enthalpy of reactant is greater than that of products.
