he mc002-1.jpgHrxn of formation of carbon dioxide is negative. Which statement is true?
The reaction is endothermic.
The reaction is exothermic.
The amount of carbon dioxide is more than the amount of reactants.
The amount of carbon dioxide is less than the amount of reactants.

Enthalpy of the reaction is defined as the total sum of the energies of the products minus the total sum of the energies of the reactants. It is represented by [tex]\Delta H_{rxn}[/tex].

If the value of enthalpy of reaction comes out to be negative, then the given reaction is exothermic reaction and if the value of positive, the reaction is endothermic reaction.

The reaction for the formation of carbon dioxide follows the equation:

[tex]C(s)+O_2(g)\rightarrow CP_2(g)[/tex]

It is given that [tex]\Delta H_f_{(CO_2)}=-ve=\Delta H_{rxn}[/tex]

The formation of carbon dioxide is equal to the enthalpy of the reaction. As, it is negative.

Hence, it is an exothermic reaction.
