If concentration are expressed in moles L^(-1) and pressure in atmosph

1.	If concentration are expressed in moles L^(-1) and pressure in atmospheres, what is the ratio of K_(p) " to " K_(c) for the reaction :2 SO_(2) (g) + O_(2) (g) hArr 2 SO_(3) (g) " at " 25^(@) C?
Answer» Solution :` Delta _(n_(g)) = n_(p) - n_(r) = -1. "Hence ", K_(p) = K_(c) (RT)^(-1) or K_(p)//K_(c)= 1//RT= 1/(00821 XX 298) = 004`
