Einsteins mass energy relation
In Einstein’s mass energy relation e = mc2 for what is c employed or why is light needed for the reactions. As the reactions are with the help of neutrons?
Expert
In this equation c is employed as a speed of light. In chemical reactions most of the reactions are photolytic reaction that signifies bond breaks or formed with the influence of light. Therefore c is employed in the reaction.
