Question

The free-energy change of a reaction is a measured of the increased molecular disorder that occurs in the system. The direction in which a net reaction occurs. The energy given off to the surroundings. The excess entropy given off to the reaction system. Arrange the acids H_2SO_3, HSO_3^- and H_2SO_4 in order of decresing strength. HSO_3^- > H_2SO_2 > H_2SO_4 H_2SO_4 > HSO_3^- > H_2SO_3 H_2SO_4 > H_2SO_4 > HSO_3^- The silver-ion in a saturated of silver(l) chromate is 1.3 times 106-4 m. What is K_sp for silver(l) chromate? 8.8 times 10^-12 1.1 times 10^-12 4.2 times 106-9 2.9 TIMES 106-16 A substance with a very low K_sp is very soluble soluble completely miscible in most solvents insoluble or sparingly soluble. Which of the following equations is correct? G = H -TS delta G = G_initial-G_final G = H - PV g = S - TH What is the concentration of silver(l) carbonate containing 0.0030 M Na_2CO_3? For Ag_2CO_3, K_sp = 8.6 times 10^-12 8.0 times 10^-9 M 5.4 times 10^-5 M 6.0 times 10^-4 M 5.4 times 10^-9 M Determine delt G degree for the following reaction: CH_4(g) + 2O_2(g) rightarrow CO_2(g) + 2H_2O(l) -919.9 kJ -682.5kJ -818.5 kJ -581.1. kJ Which of the following is not a state function?

Explanation / Answer

41. Option A is the correct answer

Free energy of the system means the total available energy present for the useful work.

The free energy depends upon the the randomness and the disorder ness of the reaction, the increased or decreased temperature and change in enthalpy.

The change in free energy depends upon the entropy of mixing . Entropy decides the change if free energy.

Hence the option A is the correct answer.
