Vedclass · Accepted Answer

$C$. for either intermolecular redox reaction or displacement reaction.

Vedclass · Answer

(C) In the given reaction: $Cr_2O_7^{2-} + H^{+} + SO_3^{2-} \longrightarrow Cr^{3+} + SO_4^{2-}$.The oxidation state of $Cr$ changes from $+6$ in $Cr_2O_7^{2-}$ to $+3$ in $Cr^{3+}$ (reduction).The oxidation state of $S$ changes from $+4$ in $SO_3^{2-}$ to $+6$ in $SO_4^{2-}$ (oxidation).Since two different elements are undergoing oxidation and reduction in separate species,this is an intermolecular redox reaction.Therefore,the correct classification is $C$.
