To derive the relation between kp and kc for a general equilibrium reaction, we get QQ(g) + rR(g) \(\rightleftharpoons\) sS(g) +tT(g)

Let us suppose there is a reversible reaction, Kc is the equilibrium constant for a reversible reaction, which depicts the ratio of the equilibrium concentrations of products over the concentrations of reactants, where each is raised to the power of their stoichiometric coefficients. We have a mole of reactant A, b mole of reactant B, c mole of reactant C, and d mole of reactant DĮxample, For 2A(g)+B(g) \(\rightleftharpoons\) 2C(g)Ĭheck out: NCERT Solutions for Class 11 Chemistry Chapter 7 Equilibrium Although it connects the pressures, it is a unitless number. It's a mathematical expression to determine the relation between product and reactant pressures. K p is the equilibrium constant determined from the partial pressure of the equation of a reaction. Partial pressures of gas components in a mixture.

Calculation of the modeled k p will automatically be performed for the chosen chemical.Ī downloadable version of the Skin Permeation Calculator is now available. The user may also browse the Flynn data base of experimental k p‘s. These models have been optimized based on experimental data compiled by Flynn. Two inputs are required: molecular weight (MW) and the base-10 logarithm of the octanol-water partition coefficient (logK ow) of the compound of interest. This calculator estimates the value of k p from an aqueous vehicle using three different models: Frasch, Potts & Guy and Modified Robinson. The skin permeation coefficient (k p) is a measure of the conductance of skin to a particular chemical from a particular vehicle.
