Calculate the heat of formation of H 2 O (l) at 90 o C from the heat of formation at 25 O C. H 2
Calculate the heat of formation of H2O (l) at 90oC from the heat of formation at 25OC.
H2(g) + O2(g) ---- H2O (l) H = -68,370 cal
The average values of the heat capacities calculated are:
Cp (H2) = 6.90 cal mol-deg
Cp (O2) = 7.05 cal/mol-deg
Cp (H2O) = 18 cal/mol-deg
