Why does every chemical reaction require a certain amount of activation energy?
2 answers:
Answer: C. Forming the activated complex requires energy.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
In order that reactants change into products, they have to cross an energy barrier. When reactant molecules absorb energy, their bonds are loosened and new loose bonds are formed between them.
The intermediate thus formed is called as activation complex. It is unstable and immediately dissociates to form stable products by release of energy.
