Questions: At t=0 s, the number of Y particles is the number of A particles. At t=60 s, the number of the Z particles is the number of B particles. 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.

Solution Steps

At \( t = 0 \, \text{s} \), we need to compare the number of Y particles to the number of A particles. Without specific numerical values or additional context, we cannot definitively determine the relationship. However, the problem implies a comparison needs to be made.

At \( t = 60 \, \text{s} \), we compare the number of Z particles to the number of B particles. Again, without specific values, we can only acknowledge that a comparison is required.

We need to compare the number of Y particles that turned into Z particles with the number of A particles that turned into B particles over the same time period. This comparison will help us understand the relative rates of the reactions.

Finally, we compare the rate of the reaction \( \text{Y} \rightarrow \text{Z} \) with the rate of the reaction \( \text{A} \rightarrow \text{B} \). This is based on the number of particles converted over the given time period.
