What is the enthalpy for the following reaction?


  • Chem -

    Look up delta H^o_f for products and reactants, then
    delta Hrxn = (delta H sum products)-(delta H sum reactants)

  • Chem -

    formation enthalpy of ethane -> –83.8 kJ/mol

    formation enthalpy of water -> −291.83 kJ/mol

    formation enthalpy of ethanol -> –277.7 kJ/mol

    I got 97.93 and got it wrong I only have one try left. I don't know whats wrong.

  • Chem -

    What phases are these reagents in? It makes a difference if they are in gas or liquid phase. The delta H is considerably different (although the differences may not be different).
