A.) Calculate K for a reaction that has ∆H⁰ = -5.65 KJ/mol and ∆S⁰ = 43.75 J/mol K at 298.15 K.

B.) Calculate ∆S⁰ for a reaction that has ∆H⁰ = 11.36 KJ/mol and K = 0.000376 at 298.15 K. Report your answer in J/mol K

C.)

Consider the reaction below.

2 NH₃ ⇋ N₂ + 3 H₂

When 1.45 M NH₃ wis allowed to decompose until equilibrium has been achieved, 0.87 M NH₃ remains. If this reaction has ∆S⁰ = 69.27 J/mol K, calculate ∆H⁰ for this reaction. Report your answer in J/mol.
