deltaS○system = Summation (n x deltaS○f(products)) - Summation (m x delta S○f(reactants))

deltaSsurr = (- deltaH○sys)/T

N2(g) + 3H2(g) -> 2NH3(g) at 298 K

a) Calculate deltaS○system

b) Calculate deltaSuniv

deltaG○ : Gibb's Free Energy

deltaG○rxn = Summation (n x deltaG○f(products)) - Summation (m x deltaG○f(reactants))

deltaGsys = deltaH○system - TdeltaS○sys

Assume that deltaH○ and deltaS○ for this reaction does NOT change with temp:

c) Calculate deltaG○f

d) Calculate the value of G○rxn at 500 C

We have a follow up homework for math due on the next meeting (which is Thursday):
