A reaction A + B has the following time dependence for the concentration of [A] vs time. For t=(0 s, 5 s, 10 s, 15 s, 25 s) the concentration of [A]=(30.00 M, 19.22 M, 12.32 M, 7.89 M, 3.24 M). The initial concentration of [A] is the value at t=0 s. (A)Calculate the values of the rate constant k assuming that the reaction is first order. 57 What is the value of k at 5 s? What is the value of k at 10 s? What is the value of k at 15 s? SZ SZ What is the value of k at 25 s? SZ (B)Calculate the value of k assuming that the reaction is second order. What is the value of k at 5 s? What is the value of k at 10 s? What is the value of k at 15 s? M-15-1 M-15-1 M-15-1 M-15-1 What is the value of k at 25 s? (C)Use your results from parts A and B above to decide what the order of the reaction is for your data. (Enter 1 or 2) (D)What is the concentration of [A] at time t=73 s? M
