Consider the dimerization 2A to A2, with forward rate constant ka and backward rate constant kb. (a) derive the following expression for the relaxation time in terms of the total concentration of protein [A]tot = [A] + 2[A2]: (1/tau^2) = kb^2 + 8kakb[A]tot (b) describe the computational procedures that lead to the determination of the rate constants ka and kb from measurements of tau for different values of [A]tot (c) use the data provided below and the procedure you outlined in part b to calculate the rate constants ka and kb, and the equilibrium constant K for formation of hydrogen-bonded dimers of 2-pyridone: [A]tot 0.500 0.352 0.251 0.151 0.101 tau 2.3 2.7 3.3 4.0 5.3

At a certain temperature and pressure 1.4 L of N2 reacts with 2.1 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 rm J/(g cdot {^circ C}) and 1.00 rm g/mL] and that no heat is lost to the calorimeter itself, nor to the surroundings.
P4(s) + F2(g)-> PF3(g) What mass of F2 is needed to produce 187 g of PF3 if the reaction has a 80.1% yield?
Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 251 units was obtained for the intensity of the 671 nm red emission line.
Draw a Lewis structure for each molecule and determine its molecular geometry. What kind of intermolecular forces are present in each substance?
write the skeleton equation representing the heating of magnesium carbonate to produce solid mangnesium oxide and carbon dioxide gas.
At 25?°C, the vapor pressure of diethyl ether is higher than the vapor pressure of its isomer n-butanol, because A. diethyl ether has a higher density than n-butanol.
STP corresponded to conditions of "standard" temperature (T=0°C) and standard pressure (p= 1 atm). At STP, 1 L of Br2 reacts totally with 3 L of F2 to form 2 L of a product. What is the formula of the product?
