    Relation Between Molar Conductivity And Equivalent Conductivity

    In physics, molar conductivity (K m ) is a physical property of matter that describes the electrical flux through a substance in units of siemens per meter squared per kelvin (S/m²/K). Equivalent conductivity (K eq ) is a related measure that accounts for the dissipation of energy in the material. Molar conductivity and equivalent conductivity are two important properties of materials that can be used to characterize their electrical properties. They are often used together to determine the material’s resistivity. Molar conductivity is useful when measuring materials in bulk or when conducting electricity through large samples. Equivalent conductivity, on the other hand, is more commonly used to characterize materials at the surface of complex assemblies or devices. It can also be used to quantify how well a material dissipates heat.

    What is Molar Conductivity?

    Molar conductivity is a measure of the ability of a material to transmit an electron through a proton blockade. Molar conductivity can be used to estimate equivalent conductivity, which is a measure of how well a material can conduct electricity. In general, molar conductivity is higher than equivalent conductivity. This is because ionic materials have higher molar conductivities than covalent materials.

    What is Equivalent Conductivity?

    There is a close relationship between molar conductivity and equivalent conductivity.
    Molar conductivity, also known as standard molar Conductance, is the measure of an material’s ability to carry electric current through it. Equivalent conductivity is a measure of how much an material can carry electric current relative to a reference material.
    Equivalent Conductivities are typically expressed in siemens per volt (S/V). This means that for every volt of applied voltage, the material can carry a specific number of siemens of electric current.
    Materials with high equivalent conductivities are often used in electrical engineering because they have the ability to transfer large amounts of electricity quickly. Materials with low equivalent conductivities, on the other hand, are often used in non-electrical applications because they have slow transmission rates.

    How are Molar and Equivalent Conductivities Used in Chemistry?

    In chemistry, molar and equivalent conductivities are commonly used to characterize the rate of a chemical reaction. The molar conductivity is the amount of charge transferred per unit time for a solution containing a substance in equilibrium with its dissolved ions. The equivalent conductivity is the reciprocal of the molar conductivity and is determined by dividing the total charge transfer by the concentration of ions in the solution.

    Molar and equivalent conductivities are important when studying reactions between molecules because they provide information about how quickly charges will be transferred between atoms. In general, substances with higher molar or equivalentconductivities will react faster than those with lower molar or equivalentconductivities. This is because substances with higher molar or equivalentconductivities are more soluble in water and will thus reach equilibrium quicker.


    Molar conductivity is closely related to equivalent conductivity. The two values are typically used together to calculate the specific heat of a substance. Molar conductivity is also important in determining the boiling point of a liquid and freezing points of solids.
