Reaction Rate Constant: Definition and Equation

WebTo calculate the rate constant, activation energy, and reaction rate, we need to use the Arrhenius equation: k = Ae^ (-Ea/RT) where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant (8.314 J/mol*K), and T is the temperature in Kelvin. Using the data provided, we can calculate the rate ... WebSo each chemical reaction has it's own rate constant, which indeed is constant, at a specific temperature. So a reaction like A -> B will have a rate constant associated with the rate law of the reaction, but we have to specify the temperature of the reaction. inward belly button https://placeofhopes.org
