I HAVE THE ANSWERS TO THESE QUESTIONS, I AM SIMPLY LOOKING FOR STEPS ON HOW TO SOLVE THEM. IF YOU ARE NOT GETTING THE CORRECT ANSWER GIVEN PLEASE DO NOT RESPOND.

- For the following reaction at 298K, if the flask contains 25 g NH4Cl, 1.2 atm NH3 and 1.8 atm HCl, then what is the free energy for the reaction under these conditions?

NH4Cl (s) <----> NH3 (g) + HCl (g) Kp= 3.06 (at 298K)

CORRECT ANSWER: -0.863 kJ

-NH4NO (s) <---> NH4+ (aq) + NO3- (aq)

Species (delta) H (kJ/mol) (delta) G (kJ/mol)

NH4NO3 -367.56 -183.87

NH4+ -132.5 -79.31

NO3- -205.0 -108.7

Why will the equilibrium constant increase as the temperature increases?

What is the equilibrium constant for this reaction at 298K and 1 atm?

CORRECT ANSWER: 5.317
