What would be the energy of activation for a reaction when a change of temperature from `20^@C " to " 30^@C` exactly triples the reaction rate constant ?

Text Solution

AI Generated Solution

To find the energy of activation (Ea) for a reaction when the temperature changes from 20°C to 30°C and the reaction rate constant triples, we can use the Arrhenius equation. Here’s a step-by-step solution: ### Step 1: Understand the Problem We are given: - Initial temperature (T1) = 20°C = 293 K (after converting to Kelvin) - Final temperature (T2) = 30°C = 303 K (after converting to Kelvin) - The rate constant at T1 is K and at T2 is 3K. ...
