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

Options

A. `2AgNO_(3)rarr2Ag+2NO_(2)+O_(2)`
B. `2AgNO_(3)rarr2Ag+N_(2)+3O_(2)`
C. `2AgNO_(3)rarr2AgNO_(2)+O_(2)`
D. `2AgNO_(3)rarr2Ag+2NO+2O_(2)`

Answer

C

Explanation

Silver nitrate decomposes to silver nitrite on heating above its melting point `(212^(@))`
`2AgNO_(3)overset(gt212^(@)C)rarr2AgNO_(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)rarr2Ag+2NO_(2)+O_(2)`
