Type of Reaction for SO2 + O2 = SO3

Описание

In this video we determine the type of chemical reaction for the equation SO2 + O2 = SO3 (Sulfur dioxide + Oxygen gas).

Since we have a two substances combining, SO2 + O2 = SO3 is a Synthesis Reaction (also called a Combination Reaction” reaction). Synthesis reactions follow the general form of:

A + B → AB

An example of a synthesis reaction is: Fe + S → FeS or Na + Cl2 → NaCl .

There is no specific number of reactants in a combination reaction.

---Type of Reactions---

Synthesis (Combination): A + B → AB
Decomposition: AB → A + B
Single Replacement : A + BC → B + AC
Double Replacement: AB + CD → AD + BC
Combustion: CxHy + O2 → CO2 + H2O
Neutralization: HX + MOH → MX + H2O
Reduction-Oxidation (Redox): Electrons are exchanged. Many of the above reactions are redox.
Endothermic and Exothermic: Reactions that take in (endo) or give off heat (exo).
Being able to determine the type of reaction by looking at reactants can help in predicting the outcome of the chemical reaction.
