Question

Match the following:

List-I (Process)		List-II (Catalyst)
A	Ostwald's process	I	\(\mathrm{CuCl_2}\)
B	Haber's process	II	\(\mathrm{V_2O_5}\)
C	Deacon's process	III	\(\text{Iron oxide, } \mathrm{K_2O,\ Al_2O_3}\)
D	Contact process	IV	Rh gauge

The correct answer is

• A. A--II, B--III, C--IV, D--I
• B. A--IV, B--I, C--II, D--III
• C. A--IV, B--III, C--I, D--II
• D. A--II, B--IV, C--I, D--III

Hint:

Remember the catalysts: \[ \boxed{ \begin{aligned} &\text{Ostwald} &&\rightarrow \text{Rh/Pt-Rh gauge}, &\text{Haber} &&\rightarrow \mathrm{Fe}+K_2O+Al_2O_3, &\text{Deacon} &&\rightarrow \mathrm{CuCl_2}, &\text{Contact} &&\rightarrow \mathrm{V_2O_5}. \end{aligned} } \]
