Question

AT&T; 12:36 PM a savstate.view.usg.edu 98% & At room temperature, the equilibrium constant (K,) for the self ionization of water is 1.00 x 10. Using this information, calculate the standard free energy change for the aqueous reaction of hydrogen ion with hydroxide ion to produce water. 7 Determine the K?for Ag,S. Knowing ??", of S2(ao is 92.1 kJ/mol; AG": of Agar, is 771 kUmol; and ?Gef of AE:Su, is-39.5 kJimol. 8. Find the ?0ì for the reaction: N2(g) + 20(g)-2NO(g). Given the AG values for the following reactions: H,0) H(g)+0(g AG 43.7 kJ Find the equilibrium constant K for the reaction: C,H,(g) +O(g) 2 CO(g+H,0(g Given the K values for the following reactions: 2C(s) + H2(g)-C,H,(g) H,(g) + O2(g) H20(g) K- 1.3x10 K=2.1x10-5 K-12x10"

Explanation / Answer

for first question

deltag= -RTlnkc

so R=gas constant,T=298k,kc=10^-14 so on substituting we get

delta= -8.314*298*ln(10^-14)=79907J
