... Initially, since A is the reactant, [A] is high and [B] is 0. At the start, the forward reaction is fast and the reverse reaction is non-existent because not enough B has built up to collide back into A. As the A gets used up, the [B] increases, and the reverse reaction speeds up. When the forward r ...
