Solid ammonium nitrate can decompose to dinitrogen oxide gas and liquid water. What is delta G at 298K?

Answer 1

Write the equation.
Balance it. Note: dGo f = free energy of formation at 25C. Then
dGofrxn = (n*dGof products) - (n*dGof reactants)
Values for dGof can be found in an appendix of most texts.

Answer 2
