equal to
At t = 0 s, the number of Y particles is
the number of A particles.
less than
At t = 60 s, the number of the Z particles is
the number of B particles.
greater than
Therefore, the number of Y particles turned into Z particles is
the number of A
particles turned to B particles for the same amount of time.
Therefore, the rate of reaction Y ? Z is
the rate of the reaction A ? B.
