Given that the slope of a ln(k) vs. 1/T plot is -2500 K, what is the activation energy for the reaction?
💡 Hint: Remember the relationship between the slope and activation energy.
If the Arrhenius constant for a reaction is found to be 1.5 x 10^10 s^-1, and the activation energy is 50 kJ/mol, what is the rate constant at 298K?
💡 Hint: Ensure all units are consistent, particularly conversion for Ea.
