Interpretation Introduction

Interpretation:

The type of chemical reaction, $2{\text{SO}}_2\left(g\right)+{\text{O}}_2\left(g\right)\to 2{\text{SO}}_3\left(g\right)$ is to be predicted.

Concept introduction:

Chemical reactions are the rearrangement of ions, atoms or molecules to form other chemical substances. The chemical substances that are used initially are known as the reactants while the newly formed chemical substances are known as the products. The chemical reaction is generally classified into four types: combination reaction, decomposition reaction, single-replacement reaction and double replacement reaction.
