Where should the label for the activation energy be added to the graph below?Reaction ProgressOA. DOB. COC. AOD. B

Answer 1

The label for the activation energy should be added to the graph below at position D. B

What is the activation energy?

The activation energy is the minimum amount of energy required for a reaction to occur. In a chemical reaction, the reactants need to come together and rearrange themselves to form new products. This rearrangement often requires them to overcome a certain energy barrier, and that barrier is the activation energy.

Catalysts can lower the activation energy of a reaction, making it easier and faster for it to occur. This metric is measured in kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).

Answer 2

INFORMATION:

We have the next graph

And we must add the label for the activation energy

STEP BY STEP EXPLANATION:

To know where is the activation energy in the graph, we need to know that:

- Activation energy: It is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy.

The formula for activation energy is

`E_a=E_{activated\text{ complex}}-E_(reactants)`

Where,

- An activated complex is an intermediate state that is formed during the conversion of reactants into products. An activated complex is the structure that results in the maximum energy point along the reaction path.

- The energy of reactants is the initial part of the graph.

Finally, since the activation energy is the difference between activated complex (maximum energy point) and the energy of reactants, we can state that the activation energy label would be located in letter B.
