Q1. Consider the following values for the question below A->B G°' = -50 kJ/mol
B->C Gº' = -23 kJ/mol
C->D Gº' = -16.8 kJ/mol
D->E G°' = 32.4 J/mol
E->F Gº' = 0.6 kJ/mol
G->M G°' = 3.6 kJ/mol
Q -> P G°' = 78 J/mol

(a) If the intracellular concentrations of the molecules C, E and Q are given below
C-19 mM
E- 12 mM
Q-76 mM

Determine the amount of ATP molecules that would be made in the cell it the reaction C -> Q was coupled to ATP synthesis. Hypothetically the temperature in
the cell is 40°C [8 marks)

Assume that the (delta)G°'= (delta)G for ATP synthesis, in the cell this is 32 kJ/mol​

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. the temperature at the start of the reaction was 23.0°c and at the end it was 19.0°c. calculate the energy absorbed by the reaction.
