Question

Give the main conditions necessary for a chemical reaction to occur?

Answer 1

Chemical reaction:

• Chemical reactions are the phenomena that involve a reaction between one or more reactants that undergo chemical change associated with absorption or liberation of energy leading to the formation of one or more new substances.

For example:

$$\begin{gathered} {\mathrm{C}}_{\left(\mathrm{s}\right)}+{\mathrm{O}}_{2\left(\mathrm{g}\right)}\to {\mathrm{CO}}_{2\left(\mathrm{g}\right)} \\ \mathrm{Carbon}\mathrm{Oxygen}\mathrm{Carbon}\mathrm{dioxide} \end{gathered}$$

The main conditions necessary for a chemical reaction to occur are:

• For a chemical reaction to take place the reactants should be brought in close contact.
• Presence of a sufficient amount of energy in the form of heat, electricity effect, light, or in the form of catalysts.
• The particle of reactants must collide with each other at the correct angle to break the bond for forming new substances.
• An optimum temperature and pressure are required.
