The activation energy for the electrochemical reaction between zinc and hydrochloric acid can be determined using the Arrhenius equation:k = A * exp -Ea / RT where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant 8.314 J/mol K , and T is the temperature in Kelvin.However, to determine the activation energy Ea for the reaction between zinc and hydrochloric acid, we would need experimental data, such as the rate constants k at different temperatures. This information is not provided in the question.If you have the rate constants at different temperatures, you can plot the natural logarithm of the rate constants ln k against the inverse of the temperature 1/T and obtain a straight line. The slope of this line is equal to -Ea/R, from which you can calculate the activation energy Ea .In summary, without experimental data, it is not possible to determine the activation energy for the electrochemical reaction between zinc and hydrochloric acid at room temperature.
