B. AHF, reactants = AHf, products
O C. AHf, reactants = 0
O D. AHF, reactants < AHt, products


Sagot :

Answer:

The answer is A

Explanation:

Just took the quiz.

The option A describes an exothermic reaction.

i.e, ΔHt,reactant > ΔHt, product

What is exothermic reaction?

The reaction in which energy is release during the formation of reaction is called exothermic reaction.

Mathematically,

ΔHf = ΔH(product) - ΔH(reactant)

For exothermic reaction, ΔHt,reactant > ΔHt, product

So,for exothermic reaction, ΔHf is negative.

Where,

ΔHf = Enthalpy of formation of reaction

ΔH(product) = enthalpy of formation of product

ΔH(reactant) = enthalpy of formation of reactant
