Five cubic meters of a 1.00-molar aqueous sulfuric acid solution (SG = 1:064) is stored at 25C.

Question:

Five cubic meters of a 1.00-molar aqueous sulfuric acid solution (SG = 1:064) is stored at 25°C. Use data in Tables B.1 and B.11 to calculate the standard heat of formation of the solution in kJ/mol H2SO4 relative to the solute elements and water, and the total enthalpy of the solution relative to the same reference conditions.


Table B.11

(AĤ.)NaOH(s) kJ/mol NaOH (AĤm)H,sO, kJ/mol H,SO, r(mol H2O/mol solute) kJ/mol HCI 0.5 -15.73 -26.22 -28.07 1.5 - 36.90 -48.82 -41.92 28.87 - 34.43 - 37.74 3 56.85 48.99 4 61.20 54.06 - 64.05 - 69.49 - 58.03 10 -42.51 -67.03 20 -71.78 42.84 - 25 -72.30 30 72.59 -42.72 -
