For the reaction:

\(\mathrm{X}_{2} \mathrm{O}_{4}(I) \longrightarrow 2 \mathrm{XO}_{2}(\mathrm{~g})\)

\(\Delta \mathrm{U}=2.1 \mathrm{k} \mathrm{cal}, \Delta 5=20 \mathrm{cal} \mathrm{~K}^{-1} \text { at } 300 \mathrm{~K}\)

Hence, ΔG is:

  1. 2.7 k cal
  2. -2.7 k cal
  3. 9.3 k cal
  4. -9.3 k cal

Answer

(D) -9.3 k cal
