As the processes state itStoichiometry, conversions, heats of reaction and catalyst windows are taken from each process's files with their provenance. The build checks only that each process's equation balances in every element, from the process's own component formulas; it does not check the numbers. A process's design maturity applies to them.

    Heat of reaction
    ΔH = -180,000 kJ/kmol at 298.15 K, as written (assumed: ASSUMED effective value to the dilute liquor (D-005): the hydrolysis to liquid H2SO4 and HCl gas (taken as about -30 kJ/mol: no sourced formation enthalpy of liquid chlorosulfonic acid was found openly), the dilution of the H2SO4 formed to about 10 wt% (of the order of -75 kJ/mol) and the dissolution of the 90 % of the HCl that stays (about -75 kJ/mol HCl); no calorimetric value of the drown-out found)
    Rate law
    basis: volume; driving: concentration; form: power_law; k: {"A":"1.78e4","Ea":40000}; orders: {"CSA":1,"H2O":1}; temperature range: 278.15 – 308.15 (assumed: ASSUMED fast effective rate (D-005): chlorosulfonic acid reacts violently with water; no open kinetics)
