Question
Recently a Mr. A. U. Ag was suspected of poisoning their rich relative, Auntie G. Richey with D-Con. The patient eventually was treated with Vitamin K1 antidote. The rate constant for eliminating the poison from her system was 8.75 x 10-4 hr -1 at 37 o C. The initial level of poisoning is 170 micrograms per liter of blood. The molar mass for the hydrophobic poison is 308.33 grams per mole. a. What is the order of the elimination process? Explain in 1-2 sentence. b. What is the general rate law expression for this process? c. Calculate the half-life for elimination of the poison from the body. d. Calculate the total time that the deliberate Vitamin K1 treatment is required to reach a safe level, 10 micrograms per liter blood. Please show explanations! test in am!Explanation / Answer
a) First order reaction
b)C = Co e^-kt
C= 170/308.33 e^-8.75 x 10-4t = 0.55 e^-8.75 x 10-4t
where C = Concentration at any time t
Co = initial concentration
k = rate constant
c) C= Co/2
ln 2 = kt
t = ln2/k = 792.168 hrs
