A) \[Fe+{{H}_{2}}S{{O}_{4}}\xrightarrow[{}]{{}}FeS{{O}_{4}}+{{H}_{2}}\]
B) \[Cu+2AgN{{O}_{3}}\xrightarrow[{}]{{}}Cu{{(N{{O}_{3}})}_{2}}+2Ag\]
C) \[2KBr+{{I}_{2}}\xrightarrow[{}]{{}}2KI+B{{r}_{2}}\]
D) \[CuO+{{H}_{2}}\xrightarrow[{}]{{}}Cu+{{H}_{2}}O\]
Correct Answer: C
Solution :
A more reactive element displace the less reactive element. The reactivity of iodine is less than bromine hence it does not displace bromine from bromide salt. Therefore, following reaction will not occur. \[2KBr+{{I}_{2}}\xrightarrow[{}]{{}}2KI+B{{r}_{2}}\]
