Discussion Overview

The discussion revolves around the reasons why sulfur trioxide (SO3) is not absorbed in water to form sulfuric acid. Participants explore various factors affecting this process, including reaction kinetics, thermodynamics, and the physical state of the products.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that the reaction does not go to completion, is slow, is highly exothermic, or is insoluble as potential reasons for the lack of absorption.
  • Another participant notes that direct absorption is dangerous due to the reactivity of SO3 with water.
  • A participant questions whether the formation of mist indicates that the reaction is exothermic.
  • A later reply expresses agreement with the previous participant's question about the exothermic nature of the reaction.

Areas of Agreement / Disagreement

Participants express differing views on the factors influencing the absorption of SO3 in water, and the discussion remains unresolved regarding which specific reasons are most significant.

Contextual Notes

The discussion includes assumptions about the nature of the reaction and the conditions under which it occurs, but these assumptions are not explicitly stated or agreed upon by participants.

Homework Statement


SO3 is not absorbed in water directly to form sulfuric acid because
A. Reaction doesn't go to completion
B. Reaction is slow.
C. Highly exothermic.
D. Insoluble

Homework Equations


--------------

The Attempt at a Solution


MY understanding: Because it results in the formation of mist or acid particles in air which does not condense easily.
From this I conclude that the answer is either C or D because the reaction does occur even though we don't get the product in the desired state and formation of mist doesn't seem slow to me...
Can anyone please clarify?

Direct absorption is kind of dangerous... it being so reactive with water and all.
 
So formation of that mist which manifests that the reaction is highly reactive means that reaction is exothermic?
 
Ooohhyeahhhh.
