125 kJ/mol is a considered a high activation energy. Based on the Arrhenius equation, the rate will be very slow if the activation energy is high due to the large energy barrier it must overcome. If the activation energy is high, then the temperature must be high in order for the rate to be fast. Room temperature isn't a very high temperature, so the reaction will not occur at room temperature.
