The table shows the rate of reaction for two unknown time intervals during a chemical change. Reaction Rates
Time Intervals (s) Rate (M/s)
T1 1.8 x 10−6
T2 1.0 x 10−6

Which of the following is true for the two time intervals? (5 points)

Select one:
a. T1 is longer than T2, and the concentration of reactants at the end of T1 is lower than that of T2.
b. T1 is longer than T2, and the concentration of products at the end of T1 is lower than that of T2.
c. T1 is shorter than T2, and the concentration of reactants at the end of T1 is higher than that of T2.
d. T1 is shorter than T2, and the concentration of products at the end T1 is higher than that of T2.
