Ammonia is synthesized according to
N2(g) + 3 H2(g) ⇌ 2 NH3(g) ΔH° = −92 kJ.
Four alternative operating strategies are proposed for a reactor already at equilibrium:
A. Decrease the volume to half its original value while keeping temperature constant.
B. Decrease the temperature by 50 K while keeping volume constant.
C. Remove NH3 continuously as it forms while maintaining temperature and volume.
D. Simultaneously decrease both the temperature by 50 K and the volume to half its original value.
Which strategy will result in the greatest final equilibrium partial pressure of NH3?
a) Strategy C
b) Strategy A
c) Strategy D
d) Strategy B
