# Calculation of number of nuclear fusion reaction per cubic meter or kilo

In wikipedia article about Nuclear fusion there is a list of nuclear fusion reaction here.

Is there a equation how to calculate number of nuclear fusion reaction per second per cubic meter or per kg or per some amount of atoms depends on pressure and temperature?

For example, I would like to calculate for first reaction Deuterium + Tritium -> Helium. How many reactions per second will happen if I have 1 kg of Deuterium + 1 kg of Tritium with temperature 1000000K and pressure 1000 atmosphere. Or any other temperature/pressure, etc.

• The important concept here is nuclear cross section. Take a look at that article, it will help you to ask a more focused question. (BTW, some of your deuterium will react with itself to produce tritium). – PM 2Ring Oct 9 '19 at 8:23
• @PM2Ring Thanks a lot. I will have a look. Actually I need very approximate number. Just to understand the order of the value, if it 10000 or 100000. For this purpose I believe reaction of deuterium with itself I can neglect. – Zlelik Oct 9 '19 at 13:23
