K₁= The equilibrium constant at absolute temperature T₁ ; K₂=The equilibrium constant at absolute temperature T₂ ;
ΔH^o= The standard enthalpy change ; T₁ & T₂ = Temperature; R= Gas constant

K_eq = Equilibrium Constant of Adsorbtion;  P = Partial Pressure or Concentration of the absorbate;  θ = The fraction of adsorbent surface covered by adsorbate

R₁ = Rate of effusion (or diffusion ) of the first gas ; R₂ = Rate of effusion (or diffusion) of the second gas; M₁ = Mass of the first gas; M₂= Mass of the second gas

K = Rate Constant;  A = Frequency Factor;  E_A = Activation Energy;  T = Temperature; R = Universal Gas Constant ;

v= Reaction Rate ; v_max =Maximum Rate ; [S] = Substrate Concentration ; K_m = Michaelis Constant
