According to le chatelier’s principle, what always happens to the equilibrium of a reaction when the temperature is reduced?

a. it shifts to the right.
b. it shifts to the left.
c. it shifts in the exothermic direction.
d. it shifts in the endothermic direction.

The correct option is C.

Explanation: Le-Chatelier's principle is a principle in which the equilibrium adjusts itself whenever there is a change in the equilibrium conditions (pressure, temperature and concentration).

When reaction is an exothermic reaction, it means that the heat is released (increase in temperature) and when it is an endothermic reaction, it means that the heat is being absorbed (decrease in temperature).

So, in a reaction, when the temperature is reduced, the equilibrium reaction will shift in the direction where there is an increase in temperature, which is the exothermic reaction.

Hence, the correct option is C.
