Consider the transmembrane fluxes of sugars. Which one of the following statements is true if we compare uniport with simple diffusion?

@X@user.full_name@X@ @GMU: What is the free energy change for the reaction below, if the reaction quotient, Q, at 25.0oC is equal to 2.14e-8?4C2H2(g) + H2(g) → C8H10(g) ΔGo = -706.560 kJ.

What is the correct equilibrium constant expression, Kp, for the following reaction?2NO2(g) + 7H2(g) ⇋ 2NH3(g) + 4H2O(g)

@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7958 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 1126.49 cm?

@X@user.full_name@X@ @GMU: From the reaction below, calculate the free energy of formation for CH4(g) at 25°C, if ΔGfo(C7H14(g)) is 95.887 kJ/mol.7CH4(g) → C7H14(g) + 7H2(g) ΔGo = 451.415 kJ/mol

@X@user.full_name@X@ @GMU: What must the reaction quotient Q be, if the free energy is -539.778 kJ at 25.0oC?3C2H2(g) → C6H6(g) ΔGo = -498.180 kJ.

@X@user.full_name@X@ @GMU: What is the coefficient, b, in the reaction below, if Kc = 4.86e-5 and Kp = 1.62e-3 at 133.41°C?3A(s) + bB(g) → 4C(g)

@X@user.full_name@X@ @GMU: A compound contains only cesium and bromine. A sample weighing 4.43 g of this compound contained 2.76 g of cesium. How many grams of bromine would there be in another sample of this compound containing 4.92 g of cesium?

@X@user.full_name@X@ @GMU: Which of the answers below is the correct representation according to the shorthand method of the following cell?2Cu+(aq) + undefined → 2Cu(s) + Ni2+(aq)

@X@user.full_name@X@ @GMU: A flexible container was filled with NO2 gas at a pressure of 1.720 atm and volume of 10.088 L. What volume would this same gas occupy if the pressure increased to 3.711 atm? Assume temperature is constant.
