Question

The Arrhenius Equation The Arrhenius Equation is typically written as k = Ae-Ea/RT However, the following more practical form of this equation also exists: where k1 and k2 are the rate constants for a single reaction at two different absolute temperatures (T1 and T2). The activation energy of a certain reaction is 37.5kJ/mol. At 20 degree C, the rate constant is 0.0130 s-1. At what temperature would this reaction go twice as fast? Express your answer numerically in degrees Celsius Given that the initial rate constant is 0.0130 s-1 at an initial temperature of 20 degree C, what would the rate constant be at a temperature of 100 degree C? Express your answer numerically in inverse seconds.

Explanation / Answer

You just need to substitute the values in the equation and solve it like for the first part k2 = 2k1 and T1 and T2 are the temperatures u need to calculate T2 from the equation.
