The following images depict the evolution of the chemical reaction YZ over time: t=Ust=40s Part A Compare the reaction YZ to the reaction AB pictured below. Which reaction has the faster rate? Compare the reaction YZ to the reaction AB pictured below. Which reaction has the faster rate? t=0st=20st=40s00s Match the words in the left column to the appropriate blanks in the sentences on the right. At t=0s, the number of Y particles is the number of A particles. At t=60s, 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 YZ is the rate of the reaction AB. If each dot represents a concentration of 0.25M, what is the rate of the reaction YZ between 0 and 20s ? Express your answer in moles per liter per second to two significant figures. 3. Incorrect; Try Again; 4 attempts remaining interval and the concentration at the final time of the interval divided by the change in time. Note that, by convention, reaction rates are reported as positive quantities. Part C If each dot represents a concentration of 0.25M, what is the rate of the reaction YZ between 40 and 60s ? Express your answer in moles per liter per second to two significant figures
