, where ∆n represents the change in the number of moles of gas in the reaction (moles gaseous products - moles gaseous reactants). When ∆n is zero (no change in number of moles of gas), the term (RT) ∆n equals 1 and Kc = Kp. When ∆n is not zero, meaning that there is a change in the number of moles of gas in the reaction, then Kc ≠ Kp. 17.26 a) Since ∆n = number of moles gaseous products - number of moles gaseous reactants, ∆n is a positive integer. If ∆n is a positive integer, then (RT) -∆n is less than 1. Thus, Kp must be larger since it is multiplied by a fraction that is less than 1 gives Kc . Kc is smaller than Kp. b) Assuming that RT > 1 (which occurs when T > 12.2 K, because 0.0821 x 12.2 = 1), Kp > Kc
