Instantaneous Rate of Change

Q. The instantaneous rate of a certain chemical reaction was determined as 2.3x10^-2 M/s at time tx and as 8.4x10^-2 M/s at time ty. We know that these two measurements were taken after 20 seconds and after 100 seconds after two reactants were mixed. tx = 20s or 100s (select one). ty = 20s or 100s (select one)
