Final answer:
To prove that the angles KAN and KSC are congruent by AAS in geometry, one would need two pairs of equal angles and one pair of equal non-included sides. The provided information does not relate to a geometric context, preventing a definitive answer.
Step-by-step explanation:
The question you have asked pertains to proving that the angles KAN and KSC are congruent by the Angle-Angle-Side (AAS) theorem in geometry. However, the information provided seems to relate instead to chemical equilibrium and the Second Law of Thermodynamics, which is not relevant to the proof required in the context of geometry.
To prove two triangles congruent by AAS, we would need two pairs of angles and one pair of corresponding non-included sides to be equal. Therefore, an additional statement that would be sufficient to prove ΔKAN ≅ ΔKSC by AAS might be that angle KAN is equal to angle KSC and the side opposite to angle K (in both triangles) is of equal length, along with another pair of angles being equal. Without the correct geometric context or diagram, it's not possible to provide a definitive answer to your specific question.
