V=_______ L
2. How many moles of a gas will occupy a volume of 0.56 L at a temperature of 349 K and a pressure of 2.6 atm ?
N=_______Mol
3. Is the change from liquid to gaseous H2O favored or unfavored by ΔH? By ΔS?
Check all that apply.
a. __unfavored by ΔS
b. __unfavored by ΔH
c. __favored by ΔS
d. __favored by ΔH
4. What are the values of ΔH (in kcal/mol and kJ/mol) for the change from gaseous to liquid H2O?
Enter your answers numerically separated by a comma.
ΔH =__________ kcal/mol, kJ/mol
5. What are the values of ΔS (in cal/(mol⋅K) and J/(mol⋅K)) for the change from gaseous to liquid H2O?
Enter your answers numerically separated by a comma.
ΔS =__________cal/(mol⋅K), J/(mol⋅K)
