Calculating equilibrium constant Kp using partial pressures (article ...
Definition of equilibrium constant Kp for gas phase reactions, and how to calculate Kp from Kc.
Writing equilibrium constant and reaction quotient expressions
The equilibrium constant, K, describes the relative amounts of reaction species at equilibrium. The expression for K is equal to the concentrations (or partial pressures) of the products raised to their …
Free energy and equilibrium (video) | Khan Academy
The standard change in free energy, ΔG°, for a reaction is related to its equilibrium constant, K, by the equation ΔG° = -RTlnK. When ΔG° < 0, K > 1, and the reaction is product-favored at equilibrium. …
Calculating the equilibrium constant from the standard cell potential
Video transcript - [Voiceover] Our goal is to calculate the equilibrium constant K for this reaction, so for this reaction right here. Now we're gonna use the standard reduction potentials to do so. So in the …
