WebFeb 12, 2024 · k is the rate constant E a is the activation energy R is the gas constant T is temperature in Kelvin A is frequency factor constant or also known as pre-exponential factor or Arrhenius factor. It indicates the rate of collision and the fraction of collisions with the proper orientation for the reaction to occur. WebThe value of the equilibrium constant is given by. Kb = [BH+][OH−] B. The greater the value of Kb, the stronger the base. For most weak acids, Kb ranges from 10−2 to 10−13. pKb = − logKb. For most weak acids, pKa ranges from 2 to 13. The smaller the value of pKb , the stronger the base. Here's a video on pKa and pKb. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch17/ph.php how old is halley\u0027s comet

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)
