I have a question. How do we know that we will get the same states in the ends if two different sets of reactions produce the same products? Though the components at the end of the reaction is same, how do we know it will always produce the same change in the state variables like temp.,pressure, volume, refractive index etc?
In this case, it's because we *require* that the product be at the same T, P, V, ... For example, maybe path 1 might have to happen at 500 K, and path 2 might have to happen at 200 K. But we have specified that our product is to be at a temperature of 298 K. So the ΔH₁ and ΔH₂ that we use must include the enthalpy change required to get the products from the reaction temperature to the specified final temperature.

Great video!! Keep going:))
Thanks! Keep watching!
