Which one of the following reactions is an example of heterogeneous catalysis?
Options
- A2 CO ( g )+ O ₂( ~g ) NO (g) 3 CO ₂
- B2 SO ₂( ~g )+ O ₂( ~g ) NO (g) 2 SO ₃
- C2 CO (g)+ O ₂( ~g ) Dt ( s ) 2 CO ₂
- DCH ₃ CHO ( g ) I ₂( ~g ) CH ₄+
Correct answer
C. 2 CO (g)+ O ₂( ~g ) Dt ( s ) 2 CO ₂
Step-by-step solution
Reaction 2 CO ( g )+ O ₂( ~g ) Pt ( s ) 2 CO ₂ is an example of heterogeneous caralysis because in it C O and O ₂ are in gaseous phase and the catalyst is in solid i.e., different phase.
