(A) Glycolysis involves ten biochemical reactions. The first two reactions of the glycolysis cycle are

Calculate the equilibrium concentration of F6P(aq) generated in the glycolysis cycle at normal body temperature, 37 °C, starting with [C₆H₁₂O₆(aq)] = 1.20 x 10^-6 M; [ATP(aq)] = 10^-4 M; and [ADP(aq)] = 10^-2 M. The equilibrium constant for the first reaction is 4.630 x 10³; for the second reaction it is 2.76 x 10^-1. During a fever body temperature increases. Will [G6P] increase or decrease with an increase with temperature?

(B) A procedure calls for adding 0.100 mol of Br₂(g) at 25 °C to a reaction. The only source of bromine in the laboratory is a bottle of liquid bromine. 

(a) Given the following data, what size container (in liters) must be used to extract enough Br₂(g) for this reaction? The equilibrium constant at 298 K for the reaction Br₂(g) ⇌ 2 Br(g) is K = 3.30 x 10^-29. The vapor pressure of liquid bromine is 0.289 atm. 

(b) At 1000 K the equilibrium constant for the reaction Br₂(g) ⇌ 2 Br(g) is 3.4 x 10^-5. What size vessel (in liters) will be needed if the temperature of the vapor is raised to 1000 K?
