In a reaction, 4 mole of electrons are transferred to 1 mole of HNO3, the possible productobtained due to reduction is:

Options

A. 0.5 mole of `N_2`
B. 0.5 mole of `N_2O`
C. 1 mole of `NO_2`
D. 1 mole of `NH_3`

Answer

B

Explanation

`2N^(5+) to (N^+)_2 + 8e`, 2 mole `HNO_3` gives one mole of `N_2O`
