We know that Kp and Kc are related for a gaseous reaction as
Kp = Kc*(RT)?n
where ?n = change in number of moles of gaseous species.
We have n = 3 moles of gaseous reactants on the right and n = 3 moles of gaseous products on the right. Therefore, we have ?n = 3 – 3 = 0 and (RT)?n = 0. Thus,
Kp = Kc*(RT)?n = (67)*(RT)0 = (67)*(1) = 67.
(C) is the correct answer.
