The energy required to break existing chemical bonds in reactants is called the activation energy.
<h3>What is activation energy?</h3>
Activation energy in chemistry is the energy required to initiate a chemical reaction.
Chemical reactions involve the breaking of chemical bonds in substances called reactants to form new substances called products.
The energy required to break the bond in the existing reactants thus elevating these substances to a state of high activation is known as activation energy.
Therefore, it can be said that energy required to break existing chemical bonds in reactants is called the activation energy.

Heat would be required : 1,670 J
<h3>Further explanation</h3>
Given
mass of H₂O=5 g
Required
Heat to melt
Solution
The heat to change the phase can be formulated :
Q = m.Lf (melting/freezing)
Lf=latent heat of fusion
The heat of fusion for water at 0 °C : 334 J/g
Input given values in formula :
