Q. Which is an example of negative catalysis?
A) $2H_{2}O_{2}\ \overset{\ \ \ Pt\ \ \ \ }{\rightarrow}\ 2H_{2}O + O_{2}$
B) $N_{2} + 3H_{2}\overset{\ \ \ Fe\ \ \ \ }{\rightarrow}\ 2{NH}_{3}$
C) $2{KClO}_{3}\ \overset{\ \ \ {MnO}_{2}\ \ \ \ }{\rightarrow}\ 2KCl + 3O_{2}$
D) $4{CHCl}_{3} + 3O_{2}\ \overset{\ \ \ C_{2}H_{5}OH\ \ \ \ }{\rightarrow}4{COCl}_{2} + 2{Cl}_{2} + 2H_{2}O$
Explanation
The correct answer is Option C: $2{KClO}_{3}\ \overset{\ \ \ {MnO}_{2}\ \ \ \ }{\rightarrow}\ 2KCl + 3O_{2}$.
