Free energy
i need help defing free energy? in the concept of a spontaneous process. is this the prcess that the reaction uses to react? how come the change of G must be -, this means that the free energy is less then the total energy therefore the reaction is unalbe to do work? HELP

lol i figured it out... lol the -^G is the final reaction of the exergonic reation, thus indicating the maximum amount of work the reaction can do.

Man, that I would have to think way back to even dredge up vague memory! Are you talking about the Gibbs- Helmholtz value delta G in Chemistry?
Defined: The free energy change is the measure of the spontaneity of a process & the useful energyavailable from it.
Basically chemical reaction involve breaking & making bonds; which may have threshold energies to overcome to react =>spontaneity for a reaction.
Not just the change in (energy) heat or entropy are driving factors of a chemical reaction.
threshold energies (frequencies) => chlorine is highly reactive to sunlight which is an important factor in swimming pools concentration of chlorine in the water.

black powder is an explosive mixture, it exist as a chemical mixture,
molecular compounds & elements. To use black powder in a gun requirers ignition (additional heat) to produce the spontaneous combustion.
The delta (^H) or change in heat content is positive or exothermal reaction, yet it doesn't happen spontaneously.
Energy added to start chemical process is generally form related & transitional phase in breaking former bonds and forming new bonds.

The environment generally supplies the energy of activiation.
As photographic (negatives) images form when salts of silver chloride & bromide react to light & then are treated with solutions (chemical procees) reduced to form metallic silver.
