The chemical reaction representing production of water gas is as follows:
calculate the enthalpy change in the production of 200L(at 500mmHg and 65degree celcius) of hydrogen by this reaction.
I think temperature will be a factor. Ignoring that
figure the moles of H2, and the moles of CO2, and the moles of H2O(l).
Now the problem. Heat of Formation is given in tables at some standard temperature, usually 273K. I hate to tell you to ignore that, as it is significant.
so would i find the moles using the ideal gas law? PV=nRT
i didn't understand the heat of formation? could you explain a little more? thanks
