Calculate the standard Gibbs energy of formation of H,O(g)at 25 °C.Method Write the chemical equation for the formationreaction, and then the expression for the standard Gibbsenergy of formation in terms of the Gibbs energy of eachmolecule; then express those Gibbs energies in terms of themolecular partition function of each species. Ignore molec-ular vibration as it is unlikely to be excited at 25 °C. Takenumerical values from the Resource section together with thefollowing rotational constants of H,O: 27.877, 14.512, and9.285 cm-1, Take for the atomization energy of H,O the value-237 kJ mol-'.

You have an initial solution in which you added quantities of “A” and “B” such that there is 4.5 M “A” and 2.5 M “B” and no complex (“AB”) at time 0. After equilibrium, you are able to isolate and quantitate the “AB” complex, and find its concentration is 1.5 M. Given that RT is 0.59 kcal/mol, what is the delta Go’ for the association reaction?
Calculate the percentage efficiency of extraction of phycocyanin in sample y, if the amount of phycocyanin is 57.8 mg, and the starting amount in sample x was 118.1 mg. Your answer should have one decimal place.
The twisted proteins store elastic potential energy as it twists or untwists from its equilibrium state. The energy function for this system is shown in the figure where the energy is given in multiples of kBT which is a unit of energy used by biochemists when working at the molecular level. (1.0 kBT = 4.11×10−21 J). Figure 6 shows a horizontal line at an energy level of 136 kBT , which gives a total angular range of 2.095 radians. If the energy level of the ATP-synthase stalk is 100 kBT instead, between what angles is the stalk confined? Explain your reasoning.

Gentiobiose has the molecular formula C12H22O11 and has been isolated from gentian root and by hydrolysis of amygdalin. Gentiobiose exists in two different forms, one melting at 86°C and the other at 190°C. The lower melting form is dextrorotatory ([α] 16°), the higher melting one is levorotatory ([α] -6°). The rotation of an aqueous solution of either form, however, gradually changes until a final value of [α] 9.6° is observed. Hydrolysis of gentiobiose is efficiently catalyzed by emulsin and produces two moles of D-glucose per mole of gentiobiose. Gentiobiose forms an octamethylether, which on hydrolysis in dilute acid yields 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4-tri-O-methyl-D-glucose. What is the structure of gentiobiose? EXPLAIN IN DETAIL.

A simple biochemical reaction with three molecules has solutions that oscillate toward a steady state when positive constants a and b are below the curve b - a = (b + a)3. Find the largest possible value of a for which the reaction has solutions that oscillate toward a steady state. (Hint: Find where da/db = 0. Derive values for a + b and a - b, and then solve the equations in two unknowns.) Source: Mathematical Biology.
