What is Arrhenius Equation?

Arrhenius equation provides an relationship between viscosity and temperature in liquids. If the viscosity of a liquid is known at two different temperatures, this information can be used to evaluate the parameters "A" and "B", which then permits the calculation of the viscosity at any other temperature.

Why Viscosity Decreases with Increase of Temperature in Liquids?

In liquids, viscosity typically decreases with an increase in temperature due to changes in molecular behavior. As temperature rises, the kinetic energy of liquid molecules increases, causing them to move more rapidly. This increased motion disrupts the cohesive forces between molecules, such as hydrogen bonding or van der Waals forces, which contribute to viscosity by impeding the flow of the liquid. As these intermolecular forces weaken with higher temperatures, the liquid molecules can move more freely past each other, resulting in lower resistance to flow and a decrease in viscosity. Additionally, the higher thermal energy at elevated temperatures can also lead to increased molecular spacing and decreased density, further reducing viscosity. Overall, the combination of weakened intermolecular forces and increased molecular motion accounts for the observed decrease in viscosity with temperature in liquids.
