    19:00 why we do not count the moles of the solid, liquid, and aqueous while we are talking about moles not volumes. And thank you.

      @@maryamghonim7669 sorry for my late reply. this case is only for gas that's why. if we have more moles of gas in the product, it means we have more randomness , which indicates higher entropy

      @@EasyChemistry4all it is ok Mr. Mouad, yea also as solids and liquids entropies are not high so they wont effect a lot?

    Thank you, we really appreciate it. In 35:05 if it’s spontaneous at lower temperatures G=negative and if it’s spontaneous at higher temperatures G=positive yes?

    • @EasyChemistry4all

      you are welcome 😊. Spontaneous means that Delta G is always negative. if H and S are both +, the G is negative when Temperature is high. of H and S are negative, the G is negative (spontaneous) when the temperature is low. i hope this helps!
