A metal catalyst $(\mathrm{X})$ is used in the catalytic converter of automobiles. This prevents the release of gas Y into the atmosphere. What are X and Y respectively?
$\mathrm{Pd}, \mathrm{NO}_2$
$\mathrm{Rh}, \mathrm{CO}_2$
$\mathrm{Pt}, \mathrm{N}_2$
$\mathrm{Ni}, \mathrm{CH}_4$
Solution
The metals used in catalytic converter art $\mathrm{Pt}, \mathrm{Pd}$, and Rh . The exhaust gases contain CO and $\mathrm{NO}_2$.
