Which one of the following reactions will occur on heating `AgNO_(3)` above its melting point ?

Options

A. a) 2AgNO_(3) to 2Ag+2NO_(2)+O_(2)`
B. b)`2AgNO_(3)to2Ag+N_(2)+3O_(2)`
C. c)`2AgNO_(3)to2AgNO_(2)+O_(2)`
D. d)`2AgNO_(3)to2Ag+2NO+2O_(2)`

Answer

C

Explanation

Silver nitrate decomposes to silver nitrite on heating above its melting point `(212^(@)C)`.
`2AgNO_(3)overset(gt212^(@)C)to2AgNO_(2)+O_(2)`
On heating above `450^(@)C` (red hot) , silver nitrate decomposes to metallic silver , oxide of nitrogen and oxygen .
`2AgNO_(3)overset(gt450^(@)C)to2Ag+2NO_(2)+O_(2)`
