A rigid 10.0 L container at 450 K is charged with N2(g) at 2.00 atm and H2(g) at 6.00 atm. The gases react completely to form NH3(g) according to
N2(g) + 3 H2(g) → 2 NH3(g)
Assuming the temperature remains 450 K, what is the total pressure in the container after the reaction is complete?
a) 2.00 atm
b) 6.00 atm
c) 4.00 atm
d) 3.00 atm
