Question

In which chemical reaction will the heat content of the reactants be more than that of the products? A: endothermic B: Reversible C: Irreversible D: Exothermic

Answer 1

I believe it's D. Exothermic.

Answer 2

Answer: The correct answer is Option D.

Step-by-step explanation:

From the given options:

Option A: Endothermic reactions are the reactions where the energy of the reactants is less than the energy of the products. The total enthalpy of the reaction is positive.
`\Delta H_(rxn)=+ve`

Option B: Reversible reactions are the reactions where reactants forming products in turn react together to give the reactants back.

Option C: Irreversible reactions are the reactions where reactants only form products and there is no turning back.

Option D: Exothermic reactions are the reactions where the energy of the reactants is more than the energy of the products. The total enthalpy of the reaction comes out to be negative.
`\Delta H_(rxn)=-ve`

Hence, the correct answer is Option D.
