The binding of oxygen to hemoglobin in the blood involves the equilibrium reaction: Carbon monoxide replaces oxygen in oxygenated hemoglobin according to the reaction: HbO2(aq) + CO(aq)HbCO(aq) + O2(aq) a. If the normal pH of blood is controlled within a range of 7.35 to 7.45. If the pKw is 13.63, what is the normal range of [H+] and [OH- b. What would happen if oxygenated hemoglobin became too acidic? c. Use the reaction and associated equilibrium constants at body temperature...
1. a) Predict the effect of the following changes on the reaction in which SO3 decomposes to form SO2 and O2. 2 SO3(g) → 2 SO2 (g) + O2 (g) delta Ho = 197.78 kJ (1) Increasing the temperature of the reaction. (2) Increasing the pressure on the reaction. (3) Adding more O2 when the reaction is at equilibrium. (4) Removing O2 from the system when the reaction is at equilibrium. b) A person exposed to high levels of carbon...
9. Carbon monoxide (CO) is toxic because it can displace oxygen (O2) from the iron in hemoglobin (Hgb) following the reaction: HgbO2 (s) + CO(g) + Hgbco (s) + O2 (g) AG®rx = -30. kl/mol A. Consider the following reactions involving hemoglobin, O2 and Co: Hgboz (s) + Hgb (s) + O2 (g) AG®rxn = 40. kJ/mol HgbCO (s) -- Hgb (s) + CO (6) AGºrx = ??? Using Hess's law, determine the free energy AG*rn (in kJ/mol) for the...
1. Carbon monoxide poisoning can happen because carbon monoxide has a higher affinity for hemoglobin than oxygen does. This can be seen by comparing the equilibrium constants for the two reactions Hb(a)+02()Hb02(aq) Hb(a)C(e) HbCO(aq) K 1.9x1012 K 1.1x1014 where Hb is hemoglobin. The actual reactions are more complicated since each hemoglobin can accept up to four oxygen molecules, but we will simplify it for this problem A concentration of about 12,500 parts per million of CO is considered highly lethal....
Carbon monoxide (CO) is toxic because it binds more strongly to the iron in hemoglobin (Hb) than does oxygen (O2), as indicated by these approximate standard free-energy changes in blood: reaction A:reaction B:Hb+O2Hb+CO⟶⟶HbO2,HbCO, ΔG∘=−70 kJ/mol ΔG∘=−80 kJ/mol Part A Estimate the equilibrium constant K at 298 K for the equilibrium HbO2+CO⇌HbCO+O2

A+B=C+D equilibrium constant can be expressed as a ratio of the concentrations: KOD AB his is an elementary chemical reaction, then there is a single forward rate and a single reverse rate for this reaction, which can be written as follows: forward rate = kr[A][B] reverse rate = k CD ere kr and ky are the forward and reverse rate constants, respectively. When equilibriums reached, the forward and reverse rates are equal ky[A] B-k CD us, the rate constants are...
