Differbetween
Kc and Kp are the equilibrium constants of gaseous mixtures. However, the difference between the two constants is that Kc is defined by molar concentrations, whereas Kp is defined by the partial pressures of the gasses inside a closed system.

What is KC and KP equilibrium constant?
c. Kp And Kc are the equilibrium constant of an ideal gaseous mixture. Kp is equilibrium constant used when equilibrium concentrations are expressed in atmospheric pressure and Kc is equilibrium constant used when equilibrium concentrations are expressed in molarity.
What is the relationship between KP and KC for the reaction below?
Answer. Kp=Kc(RT)ⁿ where R is the gas constant, T is the Temperature and n is the change in no. of gaseous moles in the reaction. NOTE: Only gaseous moles are considered.
Is KC always larger than KP?
Kp equals Kc when Δn = 0. This is true when the number of moles of gaseous products equals the number of moles of gaseous reactants in the balanced chemical equation. The value of Kp may also be less than Kc (for Δn < 0) or greater than Kc (for Δn > 0).
What is the formula of KP?
For the equation Kp = Kc(RT)^(delta N), shouldn't there be two instances in which Kp = Kc? First, when delta N = 0 (mols of product gas = mols of reactant gas); second when temperature T is the exact reciprocal of constant R or when R*T = 1 (if R = 0.08206 L*atm*mol^(-1)*K^(-1), T = 1/0.08206 K)?
Does KP depend on pressure?
Since the equilibrium constant Kp is a function of ΔGorxn which is defined for a specific composition (all reactants in their standard states and at unit pressure (or fugacity), changes in pressure have no effect on equilibrium constants for a fixed temperature.
Which of the following reaction has KP is equal to KC?
Kp only counts with gases molecule , while Kc only counts with aqueous solution+ gases. So here reactant and product both are gaseous that's why only reaction having equal numbers of reactants and products will have kp=kc ie. change in number of moles is equal to 0. option(a) is correct.
In which of the following equilibrium the value of KP is less than KC?
Solution : Kp=Kc(RT)Δn , Δn=2-(2+1)=-1 , i.e., negative, Kp<Kc . Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. The following concentrations were obtained for the formation of NH3 from N2 and H2 at equilibrium at 500K.
What temperature is KP KC?
Kc = 0.105 at 472°C.
Does KP unit?
Equilibrium constants (K, Kc, Kp) should not have units for many reasons. 1. Activities should be used not concentrations as activities are more accurate for real solutions and real gasses. Activities do not have units.
How do you calculate KC value?
Multiply concentrations of CO2 and H2O to get Kc. An important rule is that all components which are in the solid state are not included in the equilibrium constant equation. Thus, in this case, Kc=[CO2] x [H2O]=1.8 mole/L x 1.5 mole/L=2.7 mole^2/L^2.
