1.	In alkaline solution, the following equilibria exist a. `S^(2-)+S rarr S_(2)^(2-)` equilibrium constant `K_(1)` b. `S_(2)^(2-)+S rarr S_(3)^(2-)` equilibrium constant `K_(2)` `K_(1)` and `K_(2)` have values `12` and `11`, respectively. `S_(3)^(2-) rarr S^(2-)+2S`. What is equilibrium constant for the reactionA. `132`B. `7.58xx10^(-3)`C. `1.09`D. `0.918`
Answer» Correct Answer - B i. `S^(2-)+S rarr S_(2)^(2-) …k_(1)` ii. `S_(2)^(2-)+S rarr S_(3)^(2-) …k_(2)` The equation constant for the reaction, iii. `S_(3)^(2-) rarr S^(2-)+2S`, Since eq. (iii) is obtained by reversing and adding equations (i) and (ii).
