1. Letter A shows the overall enthalpy of reaction2. which is equal to kJ 2,538.90kJ 3. Letter B shows the activation energy for the reaction4. The activated complex is represented by letter C

Explanation:

1. Letter __ shows the overall enthalpy of reaction

The overall enthalpy of reaction is equal to the change of enthalpy of the substances:

Enthalpy of reaction = ∑ enthalpy of the products - ∑enthalply of the reactants.

The products are shown of the right side of the diagram. They are C₆H₁₂O₆(g) and 6O₂(g).

The reactants are shown of the left side of the diagram. They are 6CO₂(g) and 6H₂O(g).

The arrow labeled A shows the difference between the enthalpies of the products and the reactants; thus this shows the overall enthalpy of reaction.

2. which is equal to kJ__

You must subtract the enthalpy of the iniital state (reactants) from the enthalpy of the final state (products).

Overall enthalpy of reaction = - 1,273.02kJ - ( - 3,811.92kJ) Overall enthalpy of reaction = 2,538.90kJ

This is a positive change indicating the reaction is endothermic.

3. Letter___shows the activation energy for the reaction

The activation energy is the energy that the reactants must gain for the reaction occurs.

Thus, it is the difference between the maximum energy, indicated by the label C on the graph, and initial state.

That is shown by the arrow labeled B: the reactants must gain the amount of energy indicated by the arrow labeled B to reach the energy of the state labeled C.

4. The activated complex is represented by

The activated complex is the intermediate compound formed while the reactants are breaking their bonds and new bonds start to form the products. It is also called transition state.

The activated complex is on the top of the energy diagram because it hat the highest energy. The formation of the activated complex always requires energy (it is an endothermic process). Once it is formed, energy is released and the reactants are formed (this part is exothermic).

Thus, the activated complex is labeled with the letter C.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
