Question

Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product?

Part A Standard Free Energy of Formation The standard free energy of formation, AG, of a substance is the free energy change for the formation of one mole of the substance from the component elements in their standard states. These values are applicable at 25 C and are found in thermodynamic tables Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product? A, 20(s) + H2(g)C2H2(g); G 209.2 kJ/mol B. C(s)+O2(g)-CO2(8); C. C(s) + 2S(s)-CS2(g); D. 2C0(g) +02 (g)2CO2(g); Go=-788.0 kJ/mol Drag the appropriate items to their respective bins. G =-394.4 kJ/mol = 67.10 kJ/mol The value of G for a substance gives a measure of the thermodynamic stability with respect to the component elements. Negative values for a formation reaction indicate thermodynamic stability of the product. In other words, the compound formed does not spontaneously decompose back into the component elements. Positive values for a formation reaction indicate thermodynamic instability of the product. Thus, the compound will spontaneously decompose, though the rate may be slow. The sign of G! can be used to predict the feasibility of synthesizing a substance from its component elements. The standard free energy change for a reaction, AG is a state function and can be calculated from the standard free energies of formation as follows: Hints Reset Help Gron = npAGf (products) _ TzdG2 (reactants) where np and nr represent the stoichiometric coefficients in the balanced chemical equation for the reactants and products respectively Feasible synthesis Not a feasible synthesis Submit My Answers Give Up

Explanation / Answer

If delta G is positive than reaction will not be feasible and if delta G is negative than reaction will be feasible. So here reaction B and D are having delta G negatice and reaction A and C are having delta G positive.

So feasible reactions are B and D

Not feasible reaction are A and C
