Consider the following reaction:
H2O(g) + Cl 2O(g) → 2HOCl(g) K 298 = 0.090
ΔG°f = 97.9 kJ/mol
ΔH°f = 80.3 kJ/mol
S° = 266.1 J/K • mol
a. Calculate ΔG° for the reaction using the equation ΔG° = -RT ln(K).
b. Use bond energy values (Table 3-3) to estimate ΔH° for the reaction.
c. Use the results from parts a and b to estimate ΔS° for the reaction.
d. Estimate ΔH°f and S° for HOCl(g).
e. Estimate the value of K at 500. K.
