Calculate the entropy change in surroundings when 1.00 mol of H2O(l) is formed under standard conditions at 298 K. Given ΔrH0 = - 286 kJ mol−1.
From the above equation,
At 298K, when 1 mole of H2O(l) is formed, 286KJ of heat is released. The same amount of heat is absorbed by the surroundings.
As we know that,
Hence the entropy change in surroundings will be 0.96KJ/mol.
