K_p = K_c (RT) ^?n Where is number of moles of gaseous products – number of moles of gaseous reactants in the balanced chemical reaction.

so here there is only one gas molecule in product so K_p= .1 mm = 1.316 * 10^-4atm. (since 760mm=1 atm)

?n=1

so K_c= K_p/RT = (1.316 * 10^-4)/(.0821 * 300) = 5.34 * 10^-6

Thanks & Regards
