For a van der Waals gas, z=V_m/(V_m -b) - a/RTV_m. Expand the first term of this expression in a Taylor series in the limit V_m>> b to obtain z

At equilibrium, which reaction(s) will the product yield decrease with increasing temperature?

a. 2X + Y ⇌ Z              ΔH > 0

b. 2X + Y ⇌ Z              ΔH = 0

c. 2X + Y ⇌ Z              ΔH < 0
