Vedclass · Accepted Answer

$D$. for either thermal combination redox reaction or thermal decomposition redox reaction.

Vedclass · Answer

(D) The given reaction is: $(NH_4)_2Cr_2O_7 \xrightarrow{\Delta} N_2 + Cr_2O_3 + 4H_2O$.In this reaction,the oxidation state of $N$ changes from $-3$ in $NH_4^+$ to $0$ in $N_2$ (oxidation).The oxidation state of $Cr$ changes from $+6$ in $Cr_2O_7^{2-}$ to $+3$ in $Cr_2O_3$ (reduction).Since a single compound undergoes decomposition upon heating to produce redox products,it is classified as a thermal decomposition redox reaction.Therefore,the correct classification is $D$.

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
$(NH_4)_2Cr_2O_7 \xrightarrow{\Delta} N_2 \uparrow + Cr_2O_3 \downarrow + 4H_2O \uparrow$
