${ SO } _{ 2 }$ react with ${ O } _{ 2 }$ as follows :
Which of the fallowing can enhance the rate of the reaction ?
By the action of enzymes, the rate of biochemical reaction:
Rate of formation of $SO _{3}$ according to the reaction $2SO _{2}+O _{2} \rightarrow 2SO _{3}$ is $1.6 \times 10^{-3}\ kg\ min^{-1}$ Hence rate at which $SO _{2}$ reacts is :-
