When the amount of energy required to break bonds in the reactants is less than the amount of energy released in forming bonds in the products, the process has a negative change in enthalpy (−ΔH). True False

Answer :

the enthalpy of a reaction is calculated from the following formula

ΔHrxn = ∑ΔHf(products)-∑ΔHf(reactants)

Now its clear from the formula that if

a) the enthalpy of products will be more than the reaction enthalpy will be positive [endothermic reaction]

b) the enthalpy of products will be less than the reaction enthalpy will be negative [exothermic reaction]

Also

ΔHrxn = ∑Bond energies of reactants - ∑Bond energies of products

So

if bond energy of reactants [the energy required to break bond] is less than the bond energy of products the enthalpy of reaction will be negative.

When the amount of energy required to break bonds in the reactants is less than the amount of energy released in forming bonds in the products, the process has a negative change in enthalpy (−ΔH) is false.

What is enthalpy?

Enthalpy of any reaction tells about the amount of heat released or absrobed during any chemical reaction.

Change in enthalpy of any reaction will be calculated as:

ΔHrxn = ∑ΔHf(products) - ∑ΔHf(reactants)

In the question it is given that, enthalpy of products is more than the enthalpy of reactants so that we get positive value of enthalpy of reaction.

So, given statement is false.
