Title: Enthalpy Change Quic Question
Post by: Boxxxed on October 16, 2010, 02:35:37 PM

The question asks

Write the balanced chemical equation for the reaction for which the standard enthalpy change is the standard molar enthalpy change of formation at 25C for methanol CH3OH

I have

C +2H2 +1/2 O2----->CH3OH       -238.4 KJ/mol (Just got this from a chart)

Is this all I am supposed to do?

Yes, when writing a standard heat of formation equation, the reactants are in their natural state at 25C and 1atm.
