1 electron volt is equal to how many kilo joule per mole
Joule per mole 1 kJ·mol−1 is equal to 0.239 kcal·mol−1 or 1.04×10−2 eV per particle. At room temperature (25 °C, 77 °F, or 298.15 K) 1 kJ·mol−1 is equal to 0.4034    k B  T  {\displaystyle k_{B}T} .
Coulomb's constant Coulomb's constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrodynamics equations. In SI units, it is exactly equal to 7009898755178736817♠8987551787.3681764 N·m2·C−2, or roughly equaling 7009899000000000000♠8.99×109 N·m2·C−2. It was named after the French physicist Charles-Augustin de Coulomb (1736–1806) who introduced Coulomb's law.
