22. Calculate the entropy change in surroundings when 1.00 mol of H2O (l) is formed under standard conditions. ΔfH? = – 286 kJ mol–1.
22. Calculate the entropy change in surroundings when 1.00 mol of H2O (l) is formed under standard conditions. ΔfH? = – 286 kJ mol–1.
22. qrev = (-ΔfH? ) = - (- 286kJ mol-1) = 286 x 103 Jmol-1 = 286000 J mol-1
ΔS (surroundings) = qrev/ T = 286000 J mol-1 / 298 K
= 959.73 J mol-1 K-1
