Step 1
314 J/(mol·K)), - \( T \) is the temperature in Kelvin. However, since we have the rate constants at two different temperatures, we can use the following form of the Arrhenius equation to find the rate constant at the new Show more…

15) A particular first-order reaction has a rate constant of 1.35 × 10^2 s^-1 at 25.0°C. What is the magnitude of k at 75.0°C if Ea = 85.6 kJ/mol? 16) A reaction is found to have an activation energy of 108 kJ/mol. If the rate constant for this reaction is 4.60 × 10^-6 s^-1 at -1.85 ºC, what is the rate constant at 90.85 ºC?
