STD 11 - 9. Hydricarbon — NEET STD 11 Science — Question

$CO(g) + H_2O(g)  \rightleftharpoons  CO_2(g) + H_2(g)$, at a given temperature, the equilibrium amount of $CO_2(g)$ can be increased by

$2 Fe ^{2+}+ H _{2} O _{2} \rightarrow x A + y B$

(in basic medium)

$2 MnO _{4}^{-}+6 H ^{+}+5 H _{2} O _{2} \rightarrow x ^{\prime} C + y ^{\prime} D + z ^{\prime} E$

(in acidic medium)

The sum of the stoichiometric coefficients $x , y , x ^{\prime}, y ^{\prime}$ and $z ^{\prime}$ for products $A , B , C , D$ and $E ,$ respectively, is............
