Answer 2

Endothermic reaction :

When energy is absorbed as heat during a reaction it is called an endothermic reaction the heat absorbed is shown by a plus sign on the left hand side of the equation or with the negative side on right hand side.

For example :

$\sf N_{2} (g) + O_{2} (g) + 180 kJ \longrightarrow 2NO (g)$

⠀ ⠀⠀ ⠀ ⠀⠀ OR

$\sf N_{2} (g) + O_{2} (g) \longrightarrow 2NO (g) - 180 kJ$
