Q. Solid catalysts are selective in their action.
Carbon monoxide on reaction with $H _{2( g )}$ in the presence of $Cu / ZnO - Cr _{2} O _{3}$ gives compound ' $X$ ' while in the presence of $Cu$ gives compound ' $Y$ '. The difference in the molar mass of ' $X$ ' and ' $Y$ ' is ____.

Surface Chemistry

Solution:

image
Molar mass of $X$ is $32\, g\, mol ^{-1}$.
Molar mass of $Y$ is $30\, g\, mol ^{-1}$.
Difference $=32-30=2$
