Hi Peoples,

Can anyone explain to me why the gas constant is 0.0821 atm*liter/moles*Kelvin when we are using the equation Kp = Kc(RT)^n

why isn't it 8.314 J/mole*Kelvin ?

Thanks

Just for the convenience, concentration is expressed in mol/L so it is easier to use R with L, not with m³.

Note that it is the same constant, just expressed with different units. It is like stating "I am 180 cm tall" instead of "I am 5 feet 11 inches tall".

Try to convert J/mole to atm*liter/mole and you will see for yourself.
