Thermal decomposition of ammonia


ALVARO1

Recommended Posts

Hi,
I have a question and I don't know if a chemist can help me:

In table 1 on page 4 (line 8), I don't understand why there are three compounds next to the M. What does the bracket mean?

N2H3 + M [N2 (2.4); NH3 (3); N2H4 (4)] = N2H2 + H + M


(I have attached the document)

Thanks in advance,

Regards.

M typically refers to "something else", either the wall of the container, a catalyst, or another gas (or another molecule of the same gas)

Thanks for your early reply.

Yes, I understand that it is the carrier gas but what I do not understand is that it appears with three species in brackets. Why are there three compounds next to the M? Where do they come from?
