Reason : $SO_2$ is a reducing agent
Statement $I$ : The rate law for the reaction $A+B \rightarrow C$ is rate $(r)=k[A]^2[B]$. When the concentration of both $\mathrm{A}$ and $\mathrm{B}$ is doubled, the reaction rate is increased " $\mathrm{x}$ " times.
Statement $II$ :

The figure is showing "the variation in concentration against time plot" for a $"y"$ order reaction. The value of $x+y$ is . . . . . .
