Ch 8 #57
Why does the solution manual state the final units for this problem as kJ/mol, even though the units given for delta H in all other problems on reaction enthalpies (such as #61) are kJ? Are the final units for delta H in reaction enthalpy problems kJ/mol or kJ?

In 8.57 each individual enthalpy value is given in kJ/mol. Thus, I believe that the question is asking us to solve for the enthalpy for the hydrogenation of 1 mole of ethane. 8.61 gives each individual enthalpy value in kJ (possibly because it is not solving for the enthalpy of 1 mole of Bromide Gas.) I hope that this helps.

I think it might have to do with it being a reaction, so it is probably referring to the idea that you would react one mol of reactants in that theoretical reaction.
This might not be the case, but that's how I had understood it.
As far as what units needs to be used, it would depend on the context of the question, as seen with this particular question.
