Question

Please, Please Help!!!!!! The activated complex is located at point: -B -C

Answer 1

The activated complex is located at point $\boxed{\text{B}}$.

Further Explanation:

The chemical substances that were initially present at the start of a chemical reaction are called reactants whereas the ones produced after the completion of a reaction are known as products.

During the occurrence of a chemical reaction, the bonds between the reactant molecules are broken and some new bonds are formed, resulting in the formation of products. But reactants are not readily converted into products. Between these two substances, there is also a formation of a highly energetic intermediate, known as activated complex. Due to its high energy, it is very unstable and dissociates to form products. In the reaction profile diagram, it is present at the point of highest energy. So it has energy greater than both the reactants as well as products.

In the given diagram, B represents the point of highest energy so the activated complex is located at this point. Here, A represents the energy of reactant molecules, C represents the products that have energy lower than both the reactants and the activated complex and therefore its formation is possible due to lower energy and higher stability.

Answer 2

Answer : The activated complex is located at point B.

Explanation :

Activated complex : When the reactant molecules absorb energy, their bonds are loosened and new loose bonds are formed between them.

The intermediate thus formed is known as an activated complex or it is also known as transition state complex.

It is unstable and immediately dissociates to form the stable products. In the graph, it is present at the higher point.

In the given graph, A represent the reactant energy, B represent the activated complex, C represent the product, Y represent the reactant, X energy of the reaction and Z activation energy.

Hence, The activated complex is located at point B.
