Reaction Coordinate
O2 + NO2
The energy of the products is lower than the energy of the reactants.
DAE is positive.
The reaction is exothermic.
If the energy of the activated complex were increased, Ea would increase.

Expert Solution

Step 1: In this reaction a reaction profile for the first reaction is done.

SOLUTION 1:-

A . The energy level of the products is more than the energy level of the reactants. Hence,heat is absorbed in the reaction.Thus, this reaction is endothermic.

Activation energy is the energy difference between the activated complex (transition state) and reactant energy level. Hence, the value of activation energy for this reaction =411KJ

The value of $Δ$ E corresponds to the difference in energy of products and the energy of reactants =392KJ

B. Correct options:

If the energy of the activated complex is decreased, $Δ$ E is decreased.
The energy of the products is higher than the energy for the reactants.
The magnitude of the $Δ$ E for the reverse reaction is smaller than 411KJ.-
The last option is incorrect. Since the reaction is exothermic therefore
