The standard enthalpy of vaporization ∆ vap h o for water at 100 o c is 40. 66 kj mol –1. what is dg° in kj/mol? (answer in j/k mol to 3 sig figs) Specific δ h (j/g)molar δ h (kj/mol) Find your yodel. The internal energy of vaporization of water at 100 o c (in kj mol –1) is: Hence helium has a particularly low enthalpy of vaporization, 0. 0845 kj/mol, as the van der waals forces between helium atoms are particularly weak. Every substance has a characteristic specific heat, which is reported in units of cal/g•°c or cal/g•k, depending on the units used to express δ t. From the following enthalpy of reaction data and δhf∘ data, calculate δhf∘ for cac2 ( s) cac2 ( s)+2h2o (l)→ca (oh)2 ( s)+c2h2 ( g)δh∘=−127. 2 kj for h2o (l),ca (oh)2 ( s), and c2h2 ( g)δhf∘ is equal to −285. 83 kj,−986. 2 kj, and 227. 4 kj respectively.
