Give reasons for the following: At room temperature , N_2 is much lessreactive.

Answer»

Solution :Bond enthalpy of `N_2` at ROOM temperature is very high (941.4 kJ `"mol"^(-)`). This is because of the presence of one `SIGMA` and two `pi`BONDS in `N_2`.
As it is difficult to break the bond, it is much less REACTIVE at room temperature.
