At what time (in seconds) is equilibrium established?

Which of the two graphs reaches equilibrium?

Phosphorus(V) chloride decomposes at high temperatures into phosphorus(III) chloride and chlorine according to the equation.

PCl₅(g) ⇌ PCl₃(g) + Cl₂(g)

Which one of the graphs best represents the variation with pressure of the yield of chlorine at equilibrium?

Le Chatelier's Principle states that if a chemical system at equilibrium is stressed,

An exothermic reaction is allowed to reach equilibrium. If heat energy is then removed, the equilibrium will shift
