If the room on the right is like your room, does it take energy to change it to the room on the left? ree Energy and Chemical Reactions ibb’s Free Energy = G is: . Amount of energy available to do work, or . Amount of energy actually available to break and form other chemical bonds. The higher the G, the more energy is available to do work. = H – TS, where H is the chemical energy in the chemical bonds (called Enthalpy), T is the temperature in degrees Kelvin, and S is a measure of entropy. hemical Reactions Produce Changes in Free Energy...
