Equilibrium 11

⇐ To index

 

We have an equimolar mixture of two species, A₂(g) and B₂(g). They react at certain temperature, T_a, according to the following equilibrium reaction: A₂(g) + B₂(g) ⇄ 2 AB(g)

Considering that K_c= 4 for this reaction at T_a, which of the following diagrams best represents the composition of the mixture once the equilibrium has been reached?

 

	Wrong. This diagramme represent zero advance of the reaction.
	Right. This diagram represents Kc=4.
	Wrong. The advance of the reaction that represents this figure is smaller than what corresponds to a Kc=4.
	Wrong. The advance of the reaction that represents this figure is bigger than what corresponds to a Kc=4.
