The enthalpy of formation of diacetylene(C4H2)is pinpointed using state-of-the-art theoretical methods, accounting for high-order electron correlation, relativistic effects, non-Born–Oppenheimer corrections, and vibrational anharmonicity. Molecular energies are determined from coupled cluster theory with ...

Gas-phase O–H homolytic bond dissociation enthalpy in phenol, DH298°(C6H5O–H), is still disputed, despite a large number of experimental and computational studies. In estimating this value, the experimental enthalpy of formation of phenol, ΔfH298°(C6H5OH, g) = −96.4 ± 0.6 kJ/...
The standard enthalpy of formation of H2O(l) at 298 K is -285.8 kJ/mol. Calculate the change in internal energy for the following process at 298 K and 1 atm (basically at STP). The equation for formation is H2+ 0.5O2 H2O +285.8 kJ ...
