Hi
I shall calculate the enthalpy of formation of gaseous hydrogen chlorid at 298,15 K
with the usage of thw following data:
[tex] \Delta [NH_{3}+HCL ->NH_{4}] :-50,4 kJmol^{-1}
\Delta H_{form} NH_{3}:-46,2kJmol^{-1}
NHCL_{4}:-315kJmol^{-1}[/tex]
and [tex]
\Delta H_{solv} NH_{3}:-35,7kJmol^{-1}
HCL:-73,5kJmol^{-1}
NH_{4}CL:+16,4kJmol^{-1}[/tex]
I know that I need the formula that
[tex] \Delta H=\Sigma H(products) - \Sigma H(educts) [/tex]
Well to be honest I don't know where to start, our notes are just useless from the professor and I don't find anything useful on the internet. Would be nice if anyone could give me some hints.
Thanks for the help
