Kp Kc Rt N

So you have kp equals kc times rt to the delta n. Mol product tot.

N 2 o 4 l is an important component of rocket fuel at 25 circ c n 2 o 4 is a colorless gas that partially dissociates into no 2 the color of an equilibrium mixture of these 2 gasses depends on their relative proportions which are dependent on temperature.

Kp kc rt n. Above the symbols represent. The derivation of this expression uses the ideal gas equation so use b. Equilibrium is established in the reaction n 2o 4 g rightleftharpoons 2no 2 g at 25 c.

Converting between kc and kp using kp kc rt delta n. Now you re never going to be asked about the derivation of the kc kp relationship so this might be a situation like 2 where some simple rote learning of the pairings is best sufficient. Notice how it s pressure so this deals with pressures in atmospheres.

Where kp is the equilibrium constant of pressure kc is the equilibrium constant of concentration r is the universal gas constant 8 314 jmol 1 k 1 t is the temperature and δn is the difference between total moles of gas products and the total moles of gas reactants. Kp equilibrium constant using partial pressures. Kp kc rt d n.

R 0 0821 when using atm as pressure units. For 2so 3 g 2so 2 g o 2 g kc 4 08 x 10 3 at 1000 k. δ n is the change in moles.

R 0 0821 l atm mol k. So using our example kp would have been equal to the pressure of no2 gas and that quantity squared over the pressure of n2o4 gas. Kc is the equilibrium constant for molar concentration.

D n tot. Kp is the equilibrium constant and pressures. What is the difference between kc and kp.

T is temperature in kelvin. Kp kc rt d n 4 08 x 10 3 0 0821 x 1000 1. Kp kc rt δ n.

This the exponent of r and t multiplied together. T temperature in k. D n number of moles of gaseous products number of moles of gaseous reactants.

Kp kc rt δ n. K p k c rt dn d n is the difference in the number of moles of gases on each side of the balanced equation for the reaction. Kp is the equilibrium constant for pressure.

R is our old friend the gas constant from the ideal gas law section.
