    I think there is an misconception in the video. At 1:05, it is stated that if deltaG_0 is zero, the reaction is at equilibrium. This is wrong. The reaction is at equilibrium is the actual deltaG, which depends on the temperature, pressure and composition, is zero, as you correctly explain it later. By forcing actual deltaG=0, the equation deltaG_0=RTLnK is obtained.

      @shawnshields6500 7 лет назад

      Thanks for your comment, Angel. Rather than write a rather long explanation here about how deltaG is actually zero at equilibrium, it's best to go to another solid source. Here is a link to the Purdue Chemed site, and they have a great explanation of deltaG nought and deltaG in general. chemed.chem.purdue.edu/genchem/topicreview/bp/ch21/gibbs.php

    Hi Ma'am can u plz solve this problem: 2.0 g of C6H6 was burnt in excess of O2 in a bomb calorimeter : C6H6( l ) + 7½O2(g) → 6CO2(g) + 3H2O( l ) If the temperature rise is 40°C and the heat capacity of the system is 2.0 kJ/K, calculate the enthalpy of combustion of C6H6 at constant volume and constant pressure. Answer. - 2.4414 kJ/mol; -24410.283 kJ/mol

    I think there is an error at 3:26. ''If Q has a smaller value than K, it means the system has too many PRODUCTS''. Shouldn't it should be ''If Q < K,.....too many reactants''?

    Why is the 2s of Nitrogen lower than the 2s of Carbon. Judging from the periodic table, electronegativity increases from left to right. And so, shouldn't Carbon be the lowest energy of 2s rather than Nitrogen?

    • @sungjunlim1442
      @sungjunlim1442 8 лет назад

      When electronegativity is higher, then it is lower in energy which means nitrogen should be drawn lower than oxygen.

    Interesting. I'm curious what mathematical phase transitions in combinatorial problems have to do with real phase transitions. Especially where some authors claim that the phase transition in water is 'discontinuous'.

    I guess one way to remember which element has lower energy is to think of electronegativity as an "energy measurement"; that is, high electronegativity = high negative energy = low energy. At least, I like to think of it that way, haha.
