In this video we determine the type of chemical reaction for the equation SO3 + H2O = H2SO4 (Sulfur trioxide + Water). The reaction between SO3 and the HO2 H2O complex can occur in two different ways [(a) and (b)], depending on how the. HO2 H2O reactant approaches to SO3. The ... Apr 15, 2021 ... Hess' Law: rearrange the given equations to obtain the target equation. TARGET EQUATION: H2SO4(l) ==> SO3(g) + H2O(g). Given: (1) ... Jan 13, 2016 ... SO3 is an electrophile. So water molecules (a weak nucleophile) that contains exposed lone pairs attacks electron deficient center. The sulfur trioxide reacts with the water to produce sulfuric acid. SO3(g) + H2O(l) -→. ←- H2SO4(l) K = 2.2 × 10. 14. (25°C). Calculate the ∆H° for the ... In the atmosphere, this hydration reaction is regarded as the main source of gas-phase sulfuric acid.
