Question

Hello, I am wondering if there is a way to know what an elementsstandard state is by looking at some sort of trend? Also,does this relate to its melting and boiling point? I am doingstandard molar enthalpies and you must know the state of thecompound in standard state. The question is: Which of the following equations corresponds to the standardmolar enthalpy of formation of SO3? a) SO2(g) + 1/2O2(g)--> SO3(g) b) 2SO2(g) + O2-->2SO3(g) c) S8(s) + 12O2(g)-->8SO3(g) d)2S(s) + 3O2(g)--2SO3(g) e)1/8S8(g) + 3/2O2-->SO3(g) Please help!
