Kp values...help

Question

4) Carbon disulfide is a foul smelling solvent that dissolves sulfur and other nonpolar substances. It can be made by heating sulfur in an atmosphere of methane.

4CH4 (g) + S8 (s) ⇔ 4CS2 (g) + 8 H2 (g)

Starting with the following data, calculate the values of Kp for the reaction at 25 °C and
500 °C. ∆𝐻#° = 115.3 kJ/mol, ΔS°= 237.8 kJ/mol ⋅ K, and ∆𝐺#° = 65.1 kJ/mol

Answer 1

Before attempting to answer this, are you sure that ∆Sº is 237.8 kJ/mol?  ∆S values are generally given in units of J/mol. Also, I'm unsure what the # means following ∆Hº and ∆Gº.  I've not seen that before. 

 

I didn't want to go through all the calculations without being certain of what the values are.

 

You can use ∆G = ∆H - T∆S to get started.
