The activation energy for the electrochemical reaction between zinc and an acid solution that produces hydrogen gas 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/molK , and T is the temperature in Kelvin.However, to determine the activation energy  Ea  for the specific reaction between zinc and an acid solution, experimental data is required. This data typically includes the rate constant  k  at different temperatures  T . By plotting the natural logarithm of the rate constant  ln k   against the inverse of the temperature  1/T , a straight line is obtained. The slope of this line is equal to -Ea/R, from which the activation energy  Ea  can be calculated.Unfortunately, without the experimental data, it is not possible to provide the exact activation energy for the electrochemical reaction between zinc and an acid solution that produces hydrogen gas.
