The reactant concentration in a first-order reaction was 8.00×10−2 M after 15.0 s and 5.40×10−3 M after 85.0 s . What is the rate constant for this reaction?
K1 = 1/tln(a/a-x)
(1/15)ln(a/0.08) = (1/85)ln(a/0.0054)
a = initial concentration of reactant = 0.1425 M
k1 = (1/15)ln(0.1425/0.08) = 0.0385 s-1
