What is basically Gibb''s free energy change?Ans) The energy associated with a chemical reaction that can be used to do work. The free energy of a system is the sum of its enthalpy (H) plus the product of the temperature (Kelvin) and the entropy (S) of the system... DeltaG=Delta H - T Delta S
This of the following occurs when two hydrogen atoms bond with each others: (1) Potential energy is lowered (2) Kinetic energy is lowered (3) Electronic motion ceases
