K meaning chem acid
WebThe rate constant k and the reaction orders m and n must be determined experimentally by observing how the rate of a reaction changes as the concentrations of the reactants are changed. The rate constant k is independent of the reactant concentrations, but it does vary with temperature. WebThe acid dissociation constant (K a) is a quantitative measure of the strength of an acid in solution. K a is the equilibrium constant for the following dissociation reaction of an acid in aqueous solution: HA (aq) \rightleftharpoons H^+ (aq) + A^- (aq) H A(aq) ⇌ H +(aq)+A−(aq)

WebThe pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50. The lower the pKa of a Bronsted acid, the more easily it gives up its proton.
