I have a question about the following problem:

H2 + 1/2 O2 -> H2O

Determine Delta H @ 110 degrees C

Possible thoughts were to use DeltaH = m*DeltaT*SH but there's hardly any given information.

It also seems like my professor wants us to use Hess's Law, but there's no table for reactions at 110 C.

Ideas?

Thanks.

The enthalpy change of the reaction, delta H Combustion, is constant. At 110 degrees C, however, not everything is in its standard state. Maybe you'll have to consider vaporization of one of the compounds? I don't know... maybe water since it boils at 100?
