Which of the following reaction is irreversible in nature?
CH4(g)+2O2(g)→CO2(g)+2H2O(l)
NH4Cl(s)⇋NH3(g)+HCl(g)
N2(g)+3H2(g)⇋2NH3(g)
2SO2(g)+O2(g)⇋2SO3(g)
In an irreversible reaction, the reactants cannot be obtained back from the products. The arrow used in the representation of an irreversible reactions is '→'. Example of an ireversible reaction is:
CH4(g)+2O2(g)→CO2(g)+2H2O(l)
