A closed vessel initially containing gaseous reactant X\text{X}X is allowed to reach dynamic equilibrium according to the equation:
X(g)⇌2Y(g) \text{X}(g) \rightleftharpoons 2\text{Y}(g) X(g)⇌2Y(g)The concentration-time graph for the reaction is shown below:
Which statement correctly describes the state of this system?
At t1t_1t1, the rate of the forward reaction is equal to the rate of the backward reaction.
At t2t_2t2, the chemical reaction has gone to completion and both the forward and backward reactions have stopped.
At t2t_2t2, the system is in dynamic equilibrium because the rate of the forward reaction is equal to the rate of the backward reaction.
At t2t_2t2, the system is at equilibrium because the concentration of reactant X\text{X}X is equal to the concentration of product Y\text{Y}Y.
