Q. Which of the following is a heterogeneous catalysis?
A) $2C_{2}H_{5}OH\ \overset{\ \ \ \ \ Conc\ H_{2}{SO}_{4}\ \ \ \ \ }{\rightarrow}C_{2}H_{5}{OC}_{2}H_{5} + H_{2}O$
B) $2CO + O_{2}\overset{\ \ \ \ \ NO\ \ \ \ \ }{\rightarrow}\ {CO}_{2}$
C) ${SO}_{2} + \frac{1}{2}O_{2}\overset{\ \ \ \ \ {NO}_{2}\ \ \ \ \ }{\rightarrow}{SO}_{3}$
D) ${SO}_{2} + \frac{1}{2}O_{2}\overset{\ \ \ \ \ V_{2}O_{5}\ \ \ \ \ }{\rightarrow}\ {SO}_{3}$
Explanation
(d)
Equation, ${SO}_{2}(g) + \frac{1}{2}\ O_{2}(g)\overset{\ \ \ \ \ V_{2}O_{5}(l)\ \ \ \ \ }{\rightarrow}\ {SO}_{3}(g)$ is only example of heterogeneous catalysis
