Question 1

At high temperatures, boron carbide vaporizes according to

B4C(s) ⇌ 4 B(g) + C(s)


At 2500 K, the equilibrium pressure of B(g) is 0.0342 mm Hg over a mixture of 0.300 mol B4C(s) and 0.500 mol C(s). Calculate ΔG° for this process.

◦ 247 kJ

Question 2

Solid NaHCO3 is heated to 90°C. At equilibrium the total pressure of the gases produced is 0.545 atm. Calculate ΔG° at 90°C for the reaction

2 NaHCO3(s) ⇌ Na2CO3(s) + H2O(g) + CO2(g).
