Solution: The main component of acid rain (H2SO4) forms from SO2 pollutant in the atmosphere via the following series of steps:SO2 + OH• → HSO3•HSO3• + O2 → SO3 + HOO•SO3 + H2O → H2SO4Use bond energies and Hess

Problem

The main component of acid rain (H2SO4) forms from SO2 pollutant in the atmosphere via the following series of steps:
SO2 + OH• → HSO3
HSO3• + O2 → SO3 + HOO•
SO3 + H2O → H2SO4

Use bond energies and Hess's law to estimate ΔHrxn for the overall process. (Use 265 kJ/mol for the S–O single bond energy.)
