Solution: The reaction4PH3(g) ⇌ P4(s) + 6H2(g)is endothermic. In order to maximize the amount of H 2 present at equilibrium,a) raise the temperature and increase the volume.b) lower the temperature and raise the pressure with an inert gas.c) raise the temperature and decrease the volume.d) lower the temperature and increase the volume.e) lower the temperature and decrease the volume.

Problem

The reaction

4PH3(g) ⇌ P4(s) + 6H2(g)

is endothermic. In order to maximize the amount of H 2 present at equilibrium,

a) raise the temperature and increase the volume.

b) lower the temperature and raise the pressure with an inert gas.

c) raise the temperature and decrease the volume.

d) lower the temperature and increase the volume.

e) lower the temperature and decrease the volume.
