In the reversible reaction of the type, A + B ⇌ AB, in general__________________?
Correct answer: C. The combination reaction will be exothermic, while the dissociation reaction will be
- A. Both forward and backward reactions will be exothermic
- B. Neither of the reactions will be endothermic
- C. The combination reaction will be exothermic, while the dissociation reaction will be
- D. endothermic
- E. The combination reaction will be endothermic, while the dissociation reaction will be
- F. exothermic
Explanation
The combination of A and B to form AB releases the heat that is absorbed when AB dissociates. Thus, the forward combination is exothermic and the reverse dissociation is endothermic.
