Difference Between

Enthalpy vs Internal Energy For the study purposes in chemistry, we divide the universe into two as a system and surrounding. At any time, the part we are interested is the system, and the rest is surrounding. Enthalpy and internal energy are two concepts related to the first law of thermodynamics, and they describe... 

Activated Complex vs Transition State | Transition Complex vs Activation Complex When one or more reactants are converting to products, they may go through different modifications and energy changes. The chemical bonds in the reactants are breaking, and new bonds are forming to generate products, which are totally... 

Endothermic vs Exothermic Reactions Energy is the capacity to do work. In a system, energy can do work, and in this process, energy can be changed to other forms such as heat, sound, light etc. When the energy of a system changes as a result of a temperature difference between the system and the surrounding...
