2Cl^2(g) + 2H₂O_(g) 4HCl_(g) + O_2(g)
∆H° = +115KJ mol^-1. In the above equilibrium reaction, a decrease in temperature will?

The forward reaction is endothermic coz the ∆H is positive.

Increase in temperature will avoid endothermic reaction

Decrease in temperature will favour exothermic reaction

Here, since the forward reaction is endothermic, it means the backward reaction will be exothermic. Therefore the backwards reaction will be favored
A is correct
