1PRACTICE PROBLEM
The equilibrium composition of the exothermic reaction 2 L → L2 at 750 K is shown in the following figure:
Which of the following diagrams shows the equilibrium mixture after increasing the temperature of the system?
2PRACTICE PROBLEM
Two equilibrium states of the dissociation reaction PQ ⇌ P + Q at two different temperatures are shown in the diagrams below.
Identify whether the reaction is exothermic or endothermic and justify your answer using Le Chatelier's principle.
6PRACTICE PROBLEM
The initial and equilibrium state of the endothermic decomposition of P(g) molecules (purple spheres) to Q(g) molecules (orange spheres) are illustrated in the diagram below. What will happen to the number of P(g) molecules if the pressure of the system is increased by adding an inert gas?
