Annual Revision I - Chemical reactions and equations
6.
Types of chemical reaction - I
Question:
3
m.
Answer the given question:
Identify the type of each of the following reactions stating the reason for your answers.
i. \(N_2 + 3H_2 → 2NH_3\)
ii. \(2KClO_3 → 2KCl + 3O_2\)
i.
Type of reaction -
Double displacement
Decomposition
Combination
Displacement
Reason:
Nitrogen breaks down into hydrogen and forms ammonia
Hydrogen displaces nitrogen from ammonia
Nitrogen reacts with oxygen to form ammonia
Nitrogen and hydrogen molecules combine to form a compound ammonia
ii.
Type of reaction -
Combination
Displacement
Photolytic decomposition
Thermal decomposition
Reason:
\(KCl\) and \(O_2\) combines in presence of light to form \(KClO_3\)
\(KCl\) and \(O_2\) combines in presence of heat to form \(KClO_3\)
\(KClO_3\) decomposes in presence of light to form \(KCl\) and \(O_2\)
\(KClO_3\) decomposes in presence of heat to form \(KCl\) and \(O_2\)
