2NH3(g) ↔ N2(g)+3H2(g). The initial equilibrium concentration of NH3, N2 and H2 are 4 M, 1 M and 2 M

Question

Question 10 Unsaved
Consider the reaction 2NH3(g) ↔ N2(g)+3H2(g). The initial equilibrium concentration of NH3, N2, and H2 are 4 M, 1 M and 2 M respectively. Draw a graph showing the changes in the equilibrium concentrations over time. Initial concentrations should be accurate; other concentrations need to be indicated in a qualitative fashion only.

t1=some ammonia is added to the container

t2=equilibrium is achieved

t3=some nitrogen is added

t4=equilibrium is achieved

t5=the volume of the container is increased

t6=equilibrium is achieved

Answer 1

It is not possible, to my knowledge, to DRAW A GRAPH on this web site.  What I can tell you is:

t1:  Qualitatively, [NH3] increases

t2:  Qualitatively, equilibrium shifts to the right causing [N2] and [H2] to increase

t3:  Qualitatively, [N2] increases

t4:  Qualitatively, equilibrium shifts to the left causing [NH3] to increase

t5:  Qualitatively, the pressure is decreased

t6:  Qualitatively, equilibrium shift to the right causing [N2] and [H2] to increase
