The answer is C. an endothermic reaction. The endothermic reaction means this reaction will absorb energy and exothermic reaction means this reaction will release energy.
An acid dissociation constant, Ka<span>, (also known as acidity </span>constant<span>, or </span>acid<span>-ionization </span>constant<span>) is a quantitative measure of the strength of an </span>acid<span> in solution. It is the equilibrium </span>constant<span> for a chemical reaction known as </span>dissociation<span> in the context of </span>acid<span>–base reactions.
