WebIn chemistry and physics, activation energy is the minimum amount of energy that must be provided for compounds to result in a chemical reaction. The activation energy (E a) of a reaction is measured in joules per mole (J/mol), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).Activation energy can be thought of as the magnitude of the … Webf) is the test time multiplier derived from the Arrhenius equation. This equation calculates the time acceleration value that results from operating a device at an elevated temperature. The test type used to achieve this is generally referred to as High Temperature Operating Life (HTOL) or Burn-in.
