The Total solution for NCERT class 6-12
Calculate the entropy change in surroundingswhen 1.00 mol of H2O(l) is formed understandard conditions. ΔfHθ = –286 kJ mol–1.
It is given that 286 kJ mol–1 of heat is evolvedon the formation of 1 mol of H2O(l). Thus, an equal amount ofheat will be absorbed by the surroundings.
qsurr = +286 kJ mol–1
