The key difference between enthalpy and entropy is that enthalpy is the heat transfer taking place in a constant pressure whereas entropy gives an idea of the randomness of a system. For the study purposes in chemistry, we divide the universe into two as a system and surrounding. At any time, the part we are […]

The key difference between equilibrium and steady state is that in equilibrium, the concentrations of all components are being held constant whereas, in steady state, only some components are kept constant. When one or more reactants are converted to products, they may go through different modifications and energy changes. The chemical bonds in the reactants […]

The key difference between reaction rate and rate constant is that reaction rate is the speed at which reactants are converted into products whereas rate constant is a coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of the reactant or to the product of the concentrations […]

The key difference between adiabatic and polytropic processes is that in adiabatic processes no heat transfer occurs whereas in polytropic processes heat transfer occurs. In chemistry, we divide the universe into two parts. The part we are going to study is “a system”, and the rest is “the surrounding”. A system can be an organism, […]

The key difference between Adiabatic and isentropic processes is that adiabatic processes can be either reversible or irreversible, while an isentropic process is a reversible process. In chemistry, we divide the universe into two parts. The part we are interested in is a system, and the rest is the surrounding. A system can be an […]

The key difference between work and heat is that work is the ordered motion in one direction whereas heat is the random motion of molecules. Work and heat are the two most important concepts of thermodynamics. Work and heat are highly interrelated to each other but they are not quite the same. The quest to […]

The key difference between isolated system and closed system is that the isolated systems cannot exchange both matter and energy with the surrounding but, though the closed systems too cannot exchange matter with the surrounding, it can exchange the energy. For the easiness of studying chemistry, we divide the universe into two parts. The part […]

The key difference between enthalpy and heat is that enthalpy is the amount of heat transferred during a chemical reaction at constant pressure whereas heat is a form of energy. For study purposes in chemistry, we divide the universe into two: a system and surrounding. System is the subject of our investigation while the rest […]

The key difference between flash point and fire point is that the flash point describes the lowest temperature at which the ignition of a substance initiates whereas the fire point describes the lowest temperature at which the fuel continues to burn for a short time period after the initiation of the ignition.   All flammable […]

The key difference between anode and cathode is that anode is the positive terminal while cathode is the negative terminal. Anodes and cathodes are electrodes with opposite polarity. To know the difference between anode and cathode, we first need to understand what they are. Anodes and cathodes are electrodes that are used for conducting electric […]
