Concentration vs Time Graphs

N2(g) + 3H2(g) ⇌ 2NH3(g)


What would the concentration vs time graph look like if we started with our reactants?



Image illustrating Concentration vs Time Graphs



We end up with flat lines because at equilibrium, the relative concentrations of reactants and products don't change!



Practice: Concentration vs Time Graph

Consider the following graph, which was obtained by monitoring the dimerization of NO2 to N2O4.



Illustration for practice question: Practice: Concentration vs Time Graph

i. [NO2] = [N2O4] at point A;


ii. [NO2] = [N2O4] at point B;


iii. Point A is at equilibrium;


iv. Point B is at equilibrium;
