To calculate the activation energy  Ea  for the electrochemical reaction between zinc and copper sulfate, the student can use the Arrhenius equation:k = A * exp -Ea /  R * T  where:- k is the rate constant- A is the pre-exponential factor  also known as the frequency factor - Ea is the activation energy- R is the gas constant  8.314 J/mol K - T is the temperature in KelvinThe student should have experimental data for the rate constants  k  and temperatures  T  at which the reaction was performed. To determine the activation energy, the student can follow these steps:1. Convert the temperatures from Celsius to Kelvin by adding 273.15 to each temperature value.2. Take the natural logarithm  ln  of each rate constant value.3. Plot the ln k  values against the inverse of the temperature  1/T  on a graph.4. Perform a linear regression on the plotted data to obtain the slope of the line.5. Calculate the activation energy using the slope of the line and the gas constant  R :Ea = -slope * ROnce the activation energy is calculated, the student can explain its significance in terms of reaction kinetics. The activation energy represents the minimum energy required for the reactants to collide and form products in a chemical reaction. A higher activation energy means that the reaction is slower because fewer molecules have the necessary energy to overcome the activation barrier. Conversely, a lower activation energy means that the reaction is faster because more molecules have the required energy to react.In the context of the electrochemical reaction between zinc and copper sulfate, the activation energy can provide insights into the reaction's sensitivity to temperature changes. A high activation energy would indicate that the reaction rate is significantly affected by temperature, while a low activation energy would suggest that the reaction rate is less sensitive to temperature changes. This information can be useful in optimizing reaction conditions and understanding the reaction mechanism.
