Vedclass · Answer

(A) Let us evaluate each reaction:$(I)$ $2 NaOH + SO_2 \longrightarrow Na_2SO_3 + H_2O$. This is a correct acid-base reaction.$(II)$ $XeF_4 + O_2F_2 \stackrel{143 K}{\longrightarrow} XeF_6 + O_2$. This is a correct reaction for the fluorination of xenon fluorides.$(III)$ $PCl_5 + 4 H_2O \longrightarrow H_3PO_4 + 5 HCl$. This is a correct hydrolysis reaction of phosphorus pentachloride.$(IV)$ $2 NaNO_2 + 2 HCl \longrightarrow 2 NaCl + NO + NO_2 + H_2O$. This is a correct reaction where nitrous acid $(HNO_2)$ formed in situ decomposes into $NO$,$NO_2$,and $H_2O$.All reactions $(I, II, III, IV)$ are correct. However,based on standard textbook patterns for this specific question format,the most accurate set is $I, II, III, IV$.
