Determine the rate constant for each of the following second-order reactions. In each case, express your results in terms of the rate law for the loss of A.
(a) 2 A B + 2 C, given that the concentration of A decreases from 2.74 mmol·L-1 to 1.46 mmol·L-1 in 122 s.
(b) A C + 2 D, given that A0 = 0.320 mol·L-1 and that the concentration of C increases to 0.016 mol·L-1 in 210. s.
