Question 1

Consider the reaction:

N2(g) + 3 F2(g) → 2 NF3(g)       ΔH° = -249 kJ and ΔS° = -278 J/K at 25°C


Calculate ΔG° and state whether the equilibrium composition should favor reactants or products at standard conditions.
◦ ΔG° = -166 kJ; the equilibrium composition should favor reactants.
◦ ΔG° = -166 kJ; the equilibrium composition should favor products.
◦ ΔG° = -332 kJ; the equilibrium composition should favor products.
◦ ΔG° = -332 kJ; the equilibrium composition should favor reactants.

Question 2

Which statement is true about the formation of CaCO3(s) from CaO(s) and CO2(g) at 1.00 atm?

CaO(s) + CO2(g) → CaCO3(s)       ΔH° = -178.7 kJ and ΔS° = -150.4 J/K


◦ The reaction is spontaneous at low temperatures.
◦ The reaction is spontaneous at high temperatures.
◦ The reaction is spontaneous at all temperatures.
◦ The reaction is not spontaneous at any temperature.
