Based on this energy profile, the reaction is:
- Acheck_circle
Exothermic with positive Ea
- B
Exothermic with no Ea
- C
Endothermic with positive Ea
- D
Spontaneous due to negative Ea
Explanation
The peak above reactants gives a positive Ea, but products lie below reactants so ΔH < 0 (exothermic).
