Determine the enthalpy change of Reaction 3: H2SO4 (l) → H2O(l) + SO3(g) using enthalpies of formation. Apply Hess's Law to determine enthalpy change for 2NaOH + SO3 → Na2SO4 + H2O(l).

  • Hey there! Can you post these 3 parts on one problem question? You can attach them as one image (combined altogether). This way we can help you better with the solutions. Thank you! Anne commented over 1 year ago
  • Reaction 1: 2 Na + H2SO4 Na2SO4 + H2 H = -577.5 kJ Reaction 2: Na + H2O(l) NaOH + ½ H2 H = ??? Reaction 3: H2SO4 (l) H2O(l) + SO3(g) H = ??? • Determine the enthalpy change of reaction 2, in kJ/mol, given the following experimental data: When 1.50 g of sodium is placed in a calorimeter containing 40.0 g of water, the temperature increases from 22.0°C to 91.0°C. (Assume the hydrogen produced in the reaction is contained in the calorimeter and that the specific heat of the solution is the same as it is for water). In Kyung commented over 1 year ago
