059 - Using Gibbs Free Energy
In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the ΔG is less than zero the process is spontaneous. If the ΔG is greater than zero the process is not spontaneous. If the ΔG is equal to zero the process is at equilibrium. The ΔH, ΔS, and T are all used to calculate ΔG.

If I had seen Gibbs free energy explained like this when I was taking thermodynamics, the course would have made more sense.

In your example of cold pack, you state that the cold pack has taken heat from the surrounding making it cold, hence enthalpy is positive. You then state that the cold pack is made of Ammonium Nitrate in solid form and breaking it apart turns it into ammonium and nitrate ions, increasing Entropy. You next state that since the delta H value is so big, you overall will have spontaneous reaction. I'm assuming you mean delta S is big here because if delta H is very big, then the overall reaction should be nonspontaneous.

Thank you for the very clear examples of what the reactions are, ice forming or ice melting, and about the spontaneity of water forming from ice when the temperature of the water's, the system, surroundings is below freezing. You said delta H when you should have said delta S for the cold pack example.

Thank you for your comment. It is weird how a teacher can understand a thing in a way that nobody else, students, can understand it. For me to understand it I needed to understand what the reaction is. In this case their are two different reactions, the ice forming reaction and the ice melting reaction. Then I needed to understand the role of temperature on whether the reaction would occur spontaneously or not depending on the heat energy of the surroundings. So if I place ice in a surrounding temperature of 1000 degrees farenheit, the ice melting will occur spontaneously. If I place water in a surround temperature of 0 degrees kelvin, -459.67 degrees farenheit, the ice forming reaction will occur spontaneously.

@davidc1490 3 жыл бұрын

On a test, you definitely don't want to say GFE is potential energy, since in chemistry, potential energy is stored in bonds. What is really important about GFE is that it tells you if a reaction will make product or not. Some reaction rates are slow, but if you wait, the product you want will form. However, if the change in GFE, delta G, is positive, there will be no product no matter how long you might wait and hope.

(By AMA) To whom it may concern. The Key to making an over unity Electric generator work is mechanical advantage. In this case the mechanical advantage is achieved by getting the electric motor that is spinning to be able to spin a quantity of separate discs that are connected to devices that generate electrical current to generate more current then the electric motor needs to spin. One of the ways to achieve this without violating the laws of thermo dynamics is to exploit magnetic field effects. To do this you place the magnets on the disc that the electric motor is spinning in a way that makes it so while the disc is spinning around the magnetic fields are slamming upwards onto the edge of the other discs forcing them to spin, thereby generating electric current. In this way, the magnetic fields will be forced to do work that the electric motor wont be doing. This is how it's possible to achieve an Over Unity Electric generator & with this technology we can free ourselves from the use of gas. By AMA
