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 Δ
G° and state whether the equilibrium composition should favor reactants or products at standard conditions.
◦ Δ
G° = -166 kJ; the equilibrium composition should favor reactants.
◦ Δ
G° = -166 kJ; the equilibrium composition should favor products.
◦ Δ
G° = -332 kJ; the equilibrium composition should favor products.
◦ Δ
G° = -332 kJ; the equilibrium composition should favor reactants.
Question 2
Which statement is true about the formation of CaCO
3(
s) from CaO(
s) and CO
2(
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.
