Answer:

D. a relatively small fraction of the maximum number of possible hydronium ions.

Explanation:

A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution

It is produced when an Arrhenius acid dissolves in water. So a weak acid would form a relatively small fraction of the maximum number of possible hydronium ions while in contrast a strong acid would form a relatively large fraction of the maximum number of possible hydronium ions.

Answer: (d) It relatively small fraction of the maximum number of possible hydronium ions.

A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. ... At the same concentration, weak acids have a higher pH value than strong acids.

it is dissolved in water. Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than the forward one. The ions react very easily to reform the acid and the water.

Answer: The reaction is exothermic reaction as the energy of products is less than the energy of reactants.

Explanation: Exothermic reactions are defined as the reactions in which energy of the product is less than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ for the reaction comes out to be negative.

Labeling of the parts in the diagram:

A represents the activation energy which is the energy required by reactants to cross the energy barrier to get converted to products.

E represents the potential energy of the reactants.

B represents the activated complex.

D represents the potential energy of the products.

C represents the total enthalpy change of the reaction, which comes out to be negative for exothermic reactions.

$\Delta H=E_P-E_R$
