help please 10 minutes ASAP The second law of thermodynamics states that For the reaction C_2 H (g) rightarrow C_2 H_4 (g) + H_2 (g) Delta H degree is +137 kJ/mol and Delta S degree is +120 J/K mol. This reaction is Which of the following statements is true? Find the value of the equilibrium constant at 25 degree C for the reaction. Predict whether a reaction will favor the products or the reactants and explain your answer. 2NH_3 (g) +CO_2(g) NH_2 CONH_2 (aq) + H_2O (l) The standard free energy change, Delta G degree, at 25 degree C equals -13.6 kJ/mol.( Delta G degree = -RTInK, R = 8.314 J/K mol)

Explanation / Answer

1. The second law of thermodynamics states that,

c. For any sponyaneous process, the entropy of the universe increases

2. For the given reaction,

the reaction is spontaneous,

b) spontaneous only at high temperatures

3. The true statement here would be,

c) Spontaneity can depend on the temperature

4. For the given data,

lnK = 13600/8.324 x 298

K = 242.07

The reaction will favor the products.
