If the rate of reaction, `2SO_2(g)+O_2(g)overset(Pt)to2SO_3(g)` is given by :
Rate=`K([SO_2])/([SO_3]^(1//2))`
which statement are correct :

Options

A. The overall order of reaction is `-1//2`
B. The overall order of reaction is `+1//2`
C. The reaction slows down as the product `SO_3` is build up
D. The rate of reaction does not depend upon concentration of `SO_3` formed

Answer

B,C

Explanation

Over all order of Rxn =`(1-1/2)=+1/2` as `SO_3` for Rate of Rxn slow down.
