Combustion reactions are reversible in nature.
False
A reaction in which reactants give products and products can give back the reactants is known as a reversible reaction. Example of a reversible reaction is:
N2(g)+3H2(g)⇋2NH3(g)
A reaction in which reactants give products and products cannot give back the reactants is known as an irreversible reaction. Example of an irreversible reaction is:
2Mg(s)+O2(g)→2MgO(s)
The above reaction is a combustion reaction of a magnesium metal. All combustion reactions are irreversible in nature.
