QUESTION #50 Bond Enthalpy Calculation
The formation enthalpies, Δ Hf for H(g) and O(g) are 220.0 and 250.0~kJ~mol⁻¹ , respectively, at 298.15K , and Δ Hf⁻ for H₂O(g) is -242.0kJ mol⁻¹ at the same temperature. The average bond enthalpy of the O-H bond in water at 298.15K is ___________________________________________________ (nearest integer).
