Question:

Calculate the entropy change of the surroundings in each of the following reactions. Assume that the value of ΔH does not change with temperature.

a. C(s) + O₂(g) → CO₂(g) ΔH^θreaction= –393.5 kJ mol^–1
carried out at 0 °C

b. 2C(s) + N₂(g) → C₂N₂(g) ΔH^θreaction= +307.9 kJ mol^–1
carried out at 300 °C

c. H₂(g) + F₂(g) → 2HF(g) ΔH^θreaction= –271.1 kJ mol^–1
carried out at standard temperature

d. Si(s) + 2H₂(g) → SiH₄(g) ΔH^θreaction= +34.30 kJ mol^–1
carried out at –3 °C
