Determine the rate constant for each of the following first-order reactions. In each case, write the rate law for the rate of loss of A.

(a) 2 A B + C, given that the concentration of A decreases to one-fourth its initial value in 57 min

(b) 2 A B + C, given that A0 = 0.036 mol·L-1 and that after 85 s the concentration of B increases to 0.0095 mol·L-1

(c) 2 A 3B + C, given that A0 = 0.068 mol·L-1 and that after 8.2 min the concentration of B increases to 0.030 mol·L-1
