The key difference between spontaneous and nonspontaneous reactions is that the spontaneous reactions have a negative Gibbs free energy whereas the non-spontaneous reactions have a positive Gibbs free energy. Reactions can be either chemical reactions or biological reactions. We can divide these reactions into two categories as spontaneous reactions and non-spontaneous reactions. A spontaneous reaction […]

The key difference between Gibbs free energy and standard free energy is that the Gibbs free energy depends on the experimental conditions whereas the standard free energy describes the Gibbs free energy for reactants and products that are in their standard state. The terms Gibbs free energy and standard free energy are common in physical […]

The key difference between relative dating and radiometric dating is that the dating cannot provide actual numerical dates whereas the radiometric dating can provide actual numerical dates. Relative dating and radiometric dating are two types of parameters that we use to describe the age of geological features and to determine the relative order of past […]

The key difference between kinetic and end point reaction is that in kinetic reaction method, we measure the difference in absorbance between two points during the progression of the reaction whereas, in end point reaction method, we measure the total amount of analytes that participate in the reaction. The kinetic reaction method and the end […]

The key difference between heat of formation and heat of reaction is that the heat of formation is the change in enthalpy during the formation of a mole of a substance at standard conditions whereas the heat of reaction is the change in enthalpy during a chemical reaction that occurs at a constant pressure. Heat […]

The key difference between lead acid and calcium batteries is that the lead acid battery has a lead electrode inside the battery whereas the lead calcium battery has calcium along with lead as the electrode inside the battery. Because of the use of lead-calcium alloy for the electrode in lead-calcium batteries, they have a low self-discharging […]

The key difference between KJ and KCal is that KJ is the unit of measuring the energy content of a substance or a chemical reaction using joules whereas KCal is the unit measuring the energy content of a substance regarding calories. Both KJ and KCal are units that are useful in expressing the energy content […]

The key difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property. Volume is a thermodynamic state of a substance. Specific volume is a chemical concept that represents the relationship between mass and volume of a substance. The physical properties of a substance are in […]

The key difference between latent heat of fusion and vaporization is that latent heat of fusion is the amount of heat that a solid substance requires to change its phase from solid phase to liquid phase at a constant temperature whereas latent heat of vaporization is the amount of heat that a liquid substance requires […]

The key difference between colloid and emulsion is that colloid can form when any state of matter (solid, liquid or gas) combine with a liquid whereas emulsion has two liquid components which are immiscible with each other. A colloid is a mixture of a compound (that is in solid, liquid or gas state) and a […]
