Selectivity and reactivity are two important features of a catalyst

Consider the reaction given below:

\mathrm{CO ( g )+3 H _{2}( g ) {\longrightarrow} CH _{4}( g )+ H _{2} O ( g )}

In this reaction, the catalyst that selectively forms the given products from the ones given below is 

Option: 1

\text{Ni}


Option: 2

\mathrm{Cu/ZnO-Cr_2O_3}


Option: 3

\text{Cu}


Option: 4

None of these

We know starting with H2 and CO, and using different catalysts, we get different products.

\mathrm{CO ( g )+3 H _{2}( g ) \stackrel{ Ni }{\longrightarrow} CH _{4}( g )+ H _{2} O ( g )}

\mathrm{CO ( g )+2 H _{2}( g ) \stackrel{ Cu / ZnO - Cr _{2} O _{3}}{\longrightarrow} CH _{3} OH ( g )}

\mathrm{CO ( g )+ H _{2}( g ) \stackrel{ Cu }{\longrightarrow} HCHO ( g )}

So, From Ni catalyst, we get the required product.

Hence, the correct answer is Option (1)
