Question

What is the activation energy in Joules for a chemical reaction that has a rate constant of 2.7 x 10^-3 s^-1 and a temperature of 298 K? The activation energy can be calculated using the Arrhenius equation.

Answer 1

To calculate the activation energy  Ea  using the Arrhenius equation, we need the rate constant  k , the temperature  T , and the pre-exponential factor  A . The Arrhenius equation is:k = A * exp -Ea /  R * T  where R is the gas constant  8.314 J/mol*K .However, we don't have the pre-exponential factor  A  given in the problem. Therefore, we cannot directly calculate the activation energy  Ea  using the Arrhenius equation with the given information.
