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?

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.
i. [NO2] = [N2O4] at point A;
ii. [NO2] = [N2O4] at point B;
iii. Point A is at equilibrium;
iv. Point B is at equilibrium;
Which of the following statements are true?
Practice: Concentration Vs Time Graphs
Use the following reaction to answer the following questions:
2SO2(g) + O2(g) ⇌ 2SO3(g)
Below is a concentration-time graph..
