What is the frequency factor and where can we get values for it? What is it dependent on?
Generally the frequency factor is independent of temperatures, however on occasion it can be a weak function of temperature. See p.944 • Why is the limiting reactant our basis of calculation? One could calculate a NEGATIVE concentration otherwise. See Example 3-5 (p.90). • What is the relationship between the K in chemistry (A + B C) and the k in the rate laws? KC is an equilibrium constant, and k is specific rate constant. k has units of time, K does not. • How does the k (specific reaction rate) depend on pressure, or does it? ONLY in very very rare instances at very high pressures such as, 6000 atm, for liquid phase reactions is k a function of pressure. See p.220 and CD-ROM on critiquing what you read. • What is the frequency factor, A, in the Arrhenius Equation; I want to know what it’s physical meaning is and/or what it is a frequency factor. Arrhenius Equation is k = Ae-E/RT The frequency factor, A, is the coefficient of the exponential term. It has the same units as k. It is re
