Q. Solid catalysts are selective in their action.
Carbon monoxide on reaction with $H_{2 (g)}$ in the presence of $C u / Z n O - C r_{2} O_{3}$ gives compound ' $X$ ' while in the presence of $C u$ gives compound ' $Y$ '. The difference in the molar mass of ' $X$ ' and ' $Y$ ' is ____.

Molar mass of $X$ is $32 g m o l^{- 1}$ .
Molar mass of $Y$ is $30 g m o l^{- 1}$ .
Difference $= 32 - 30 = 2$

Q. Solid catalysts are selective in their action. Carbon monoxide on reaction with H2(g)​ in the presence of Cu/ZnO−Cr2​O3​ gives compound ' X ' while in the presence of Cu gives compound ' Y '. The difference in the molar mass of ' X ' and ' Y ' is ____.

Molar mass of X is 32gmol−1. Molar mass of Y is 30gmol−1. Difference =32−30=2
