The enthalpy of formation has a negative sign, which means that the reaction is exothermic. In other words, when ethanol is formed, heat is released to the surroundings as a by-product. The reaction for the formation of ethanol is written below:
<em>C₂H₄ + H₂O → C₂H₅OH</em>
This would support Dalton's postulates that says atoms are indivisible because there are no smaller particles than the atoms.
Explanation:
If during Thomson's cathode rays experiment, the size of the particles produced is the same as the size of the atom forming the cathode, it would perfect corroborate with Dalton's postulate.
- John Dalton believed the simplest substance of any matter is an atom.
- An atom is indivisible and cannot be broken down.
- From his atomic theory, matter does not any other smaller particles besides atom.
- If the size of the atoms of rays and that of the cathode were to be the same, this would have supported his claim.
