Question

Formation of ammonia from and $N _ { 2 }$ by Haber's process using is an example of.

• A. Heterogeneous catalysis
• B. Homogeneous catalysis
• C. Enzyme catalysis
• D. Non-catalytic process

Answer 1

Answer: (A)

Heterogeneous catalysis

Answer 2

Sol The catalytic process in which the reactants and the catalyst are in different phases is known as heterogenous catalysis.

$\mathrm { N } _ { 2 ( \mathrm {~g} ) } + 3 \mathrm { H } _ { 2 ( \mathrm {~g} ) } \xrightarrow { \mathrm { Fe } ( \mathrm { s } ) } 2 \mathrm { NH } _ { 3 ( \mathrm {~g} ) }$

The reactants are in gaseous state while the catalyst is in solid state.
