10 Ammonia is manufactured using the process shown in Equation 10.1.
A high pressure and moderate temperature are used.
N2(g) + 3H2(g) 2NH3(g) ∆H = –92kJmol–1 Equation 10.1
What is correct about this manufacturing process?
A Creating a high pressure is expensive and dangerous.
B If the process were attempted at room temperature it would be quicker but give less
ammonia.
C The nitrogen gas is expensive.
D The process is beneficial to society because it removes nitrogen from the air.
