Question:Consider a chemical reaction between two gaseous reactants, A and B, to form a single gaseous product, C. The reaction is known to be highly exothermic and proceeds at an extremely fast rate. However, it is observed that the reaction does not occur spontaneously under standard conditions, even though the products are energetically favored. Explain this discrepancy and provide a possible explanation for the reaction's behavior.
