For the equilibrium A₂(g) 2A(g),if a sample of A₂(g)is placed in a sealed container and allowed to come to equilibrium,which graph best represents the relationship between Q_c and time as equilibrium is established?

Initially, there is no product A present in the system so the rate of its formation is zero. The concentration of the reactant, A₂, will decrease with time as it is consumed to form A until it reaches equilibrium. At equilibrium, the rate of formation of A and rate of consumption of A will be equal, leading to a constant concentration of A. Thus as time progresses, the concentration of reactant will decrease and concentration of A will increase until it reaches a constant value at equilibrium. This is best represented by graph C, where the concentration of reactant decreases with time and concentration of A increases until it reaches a constant value at equilibrium.
