Can the thermochemical equation of synthetic ammonia reaction be spontaneously carried out at room temperature?

As a reversible reaction, I can tell you for sure that both sides of this reaction can be carried out at room temperature. But at room temperature, even at high temperature, the speed of positive reaction is very slow, so slow that there is no yield at all. As an important link in the industrial production of synthetic ammonia, the most important thing is high yield, so high temperature and high pressure catalyst has become a tradition. If you want to see the reaction phenomenon in the experiment, there is no certain reaction condition, and I believe the effect of the reaction is not obvious.
