Question:Consider a hypothetical reaction A + B ⟶ C, where A and B are reactants and C is the product. The reaction is known to be exothermic and has a negative value for the enthalpy change (ΔH < 0). However, upon conducting the reaction in a laboratory setting, it is observed that the reaction does not occur spontaneously at room temperature (25°C). Explain this apparent contradiction and propose a possible explanation for this behavior
