Ans: Activity is a measure of a species ‘ active concentration under conditions that are not optimal (e.g., concentrated). This determines, rather than an idea, the real chemical potential for a real solution.

Ans: Usually active mass in units of mol dm3 is known to be the molar concentration; expressed as square brackets.  [ ].

Ans: Law of mass action, the law stating that the frequency of any chemical reaction is proportional to the sum of the masses of the reacting materials, each mass being elevated to a power equal to the coefficient in the…

Ans: Kc and Kp are the constants of the equilibrium of gas mixtures. The distinction between the two constants, however, is that Kc is determined by molar concentrations, while Kp is defined by the gasses ‘ partial pressures within a…

Ans: Mass action law states that a chemical reaction frequency is proportional to the active masses of reacting materials at a constant temperature. Kc is the reaction constant of equilibrium, while Kp is the constant of equilibrium found by applying…
