What is the Kp Equilibrium Constant Calculator & How does it work?
The equilibrium constant, Kp, is a quantitative measure used in chemistry to describe the extent to which a chemical reaction proceeds towards completion. It is specifically defined for reactions involving gases and relates the partial pressures of the reactants and products at equilibrium.
For a general gas-phase reaction:The expression for Kp is given by:
For a general gas-phase reaction:
aA(g) + bB(g) ⇌ cC(g) + dD(g)
a, b, c, d = stoichiometric coefficients
A, B, C, D = gases involved in the reaction
A, B, C, D = gases involved in the reaction
K_p = \frac{(P_C)^c (P_D)^d}{(P_A)^a (P_B)^b}
PA, PB, PC, PD = partial pressures of gases A, B, C, and D at equilibrium
