Q.
Formation of ammonia from $H _{2}$ and $N _{2}$ by Haber's process using $Fe$ is an example of
J & K CETJ & K CET 2005
Solution:
In heterogeneous catalysis, the reactant and the catalyst are in different phases.
$ N_{2}(g)+3H_{2}(g)2NH_{3}(g) $
In the Haber's process the reactants are is gaseous phase while catalyst $(Fe)$ in solid phase.
Hence, it is an example of heterogeneous catalysis.
