Question

The numerical value of $K_c$ increases or decreases with temperature and it depends upon the heat of reaction whether it is endothermic or exothermic .
If true enter 1, else enter 0.

Answer 1

The numerical value of $K_c$ increases or decreases with temperature and it depends upon the heat of reaction whether it is endothermic or exothermic. When, the equilibrium shifts in forward direction, the $K_c$ value increases. When, the equilibrium shifts in the backward direction, the $K_c$ value decreases.

Nature of the reaction	Temperature	Shift of equilibrium to
Exothermic	Increased	backward direction
Exothermic	Decreased	forward direction
Endothermic	Increased	forward direction
Endothermic	Decreased	backward direction

In exothermic reaction, heat is evolved and in the endothermic reaction, heat is absorbed.
