For those wondering, "What is equilibrium constant?", the equilibrium constant definition is: the product-to-reactant ratio in a reversible reaction at which there will be no net change in the concentrations. The equilibrium constant (K,Kc,KP, or Keq) is temperature-dependent, so its value ...
For the reaction 4/3Al + O2 = 2/3Al2O3, the equilibrium constant is given by K = [Al2O3]2/3/[Al]4/3[O2], where [] denotes concentration. Note that the concentration is raised to a power equal to the number of molecules (or atoms) participating in the reaction. The free ...

where M is the trace metal, L the ligand, m and n the valencies of the metal and ligand, respectively, and a and b the stoichiometric constants. The equilibrium constant for this reaction (K) can be written as (2)K=[(Mm+)(Ln−)b]/[(MaċLb(S)] or in its log form as (3...
The equilibrium Xe + 2Ar has been investigated in the temperature range 150–300 K using a selected ion flow tube appratus. From the temperature variation of the equilibrium constant the standrad enthalpy change for the reaction is determined to be 25 ± 5 kj mol 1 and the dissociation energ...
What is the difference between K and Q? The equilibrium constant (K) differs from the reaction quotient (Q) in that K uses the concentrations at equilibrium while Q can use the concentrations at any given time. Additionally, the value of Q changes during a reaction, whereas the value of ...
