Heat of Dilution for H2SO4

Heat of Dilution for H2SO4

Heat of Dilution for H2SO4

I am unable to find a suitable value for Heat of Dilution of concentrated H2SO4. I will share my calculation here as well but first I need this value to be settled.

I have x2 documents
1] 95 kJ/mol https://scilearn.sydney.edu.au/firstyear/exams/che...
2] 71.76 kJ/mol http://dpuadweb.depauw.edu/harvey_web/Chem260/Chem...

Background: I am determining cooling load while drying wet Cl2 gas using circulated H2SO4 in a drying packed tower (98w.t% > 78w.t%)


RE: Heat of Dilution for H2SO4

Can anyone check my calculations. Especially the part where I calculated the amount of hydrated acid ..bcz this is directly linked with heat generated

Thank pierreick for the help!

RE: Heat of Dilution for H2SO4

pierreick (Chemical),
Extremely thanks for the resource. BTW the last one is valid upto 10 wt% of acid & I am handling 78 - 98%
However, your literature proved highly helpful. A side observation:

p-17 of your 2nd last resource. Why the metal loss is highest b/w 80-83wt% of acid while it lowers again at below concentrations than this. Any microscopic stuff happening here?
