For the reaction of A + B ⇄ C + D + heat, the reverse reaction is exothermic.
Group of answer choices
True or False
The given reaction is exothermic as the heat is liberated in the reaction on the product side. So, the given reaction in the reverse direction is exothermic as heat will be added to C+D, when the reaction proceeds in the reverse direction. So, this false statement.
