Which of the following is primarily responsible for limiting the number of trophic levels in most ecosystems?
a) 45.0 moles of H2
b) 33.8 moles of H2
c) 15.0 moles of H2
d) No matter how many moles of H2 are added, 30.0 moles of NH3 cannot be produced.
d) No matter how many moles of H2 are added, 30.0 moles of NH3 cannot be produced.
Answer: 14.5 moles of N2 can only produce a maximum of 29.0 moles of NH3, regardless of how much H2 is added to the reaction.
14.5 moles N2 x (2 mol NH3/1 mol N2) = 29 mol NH3
