Take any two points from the table (for example, the two at the top) to determine the rate constant: k=t[AB]50s1[AB]0s1=50s0.459M10.950M1=0.0225M1s1 Part C Predict the concentration of AB at 24s. Express your answer in moles per liter to three significant figures. X Incorrect; Try Again Use the second-order integrated rate law and solve it for the concentration of [AB] at 24s : [AB]t1=kt+[AB]01 where [AB]t is the concentration of AB at any time t,k is the rate constant, and [AB]0 is the initial concentration of AB
