a. Decide whether the reaction below is spontaneous in the
forward direction
(towards NH3) when the partial pressure of NH3(g),
H2(g), and N2(g) is equal to 20
atm, 15 atm, and 25 atm, respectively, at 25 oC.
N2 (g, 25 atm) + 3H2(g, 15
atm) ⇌ 2NH3 (g, 20atm)



b. The melting point (Tm) of ethanol (CH3CH2OH) is equal
to 158.7 K and the melting
enthalpy (fusion enthalpy, ∆Hfus) of ethanol is equal to
4.60 kJ/mol. Calculate the
melting entropy (fusion entropy, ∆Sfus) of ethanol at
158.7 K. (The melting process is outlined below)
CH3CH2OH(s) ⇌
CH3CH2OH(l)
