J/(mol.K) SUBMIT ANSWER < 05/14 > 7 OF 14Q

Answer 1

(1) The change in entropy of Cu = entropy of Cu(g) - entropy of Cu(s)

= 166.4 J/mol K - 33.2 J/mol K

= 133.2 J/mol K

(2)

The change in entropy of Br₂ = entropy of Br₂(g) - entropy of Br₂(l)

= 245.5 J/mol K - 152.2 J/mol K

= 93.3 J/mol K

(3)

The change in entropy of Br₂(l) = 2 * entropy of Br(g) - entropy of Br₂(l)

= 350 J/mol K - 152.2 J/mol K

= 197.8 J/mol K
