Question

In a chemical reaction, the difference between the potential energy of the products of the potential energy of the reactants is equal to the .

a)activation energy .
b)entropy of the system.
c)heat of fusion.
d)activation energy

Answer 1

In a chemical reaction, the difference between the potential energy of the products and the potential energy of the reactants is equal to the heat of the reaction. This is, the net energy released or absorbed (change) during a chemical reaction is the sum of the potential energy of the products less the sum of the potential energy of the reactants.
