Answer 2

Answer:

According to Le Chatelier's principle :

If a system is in equilibrium if we disturb the equilibrium by increasing or decreasing concentration , pressure or temperature then it shift in such a way to undo the effect.

Given :

A + B  ⇆  C + D

The change in enthalpy Δ H = - 10 k cal

As the reaction is exothermic hence on adding heat would be move in the backward direction.
