2.a) -137 J/K due to 3 moles of gas going to 2. b) 285 KJ for Enthalpy, 326 for Free Energy, Non Spontaneous
c) 163 KJ d)-1480 KJ and 1.28 V e) Find STD Free Energy or STD Voltage at new T, then calculate K.

3. See CPR #3 and your lab observations

4. .740 V, -428 KJ b) see lab c) delta G = 0, use STD delta G to find K = 1.06 x 10^75
d) Use Enthalpy and Entropy to find G at 198, then find K, Find voltage at 198, then find G and K.
