write the equilibrum constant expression for Kp of the following:
a.) O2-->--<2O3(g)
b.)SiH4(g) + 2O2(g)-->--<SiO(s) + 2H2O(g)
c.)MgO(s) + SO2(g) + O2(g)-->--<MgSO4(s)
d.)2PbS(s) + 3O2(g)-->--< 2PbO(s) + 2SO2(g)

This is a fundamental concept that you need to know how to do yourself. If you will explain what you don't understand I ca help you through it. Basically it's partial pressure of products over partial pressure reactants with coefficients becoming exponents. Solids are not included in Kc OR Kp. Pure liquids aren't either.
