Consider the reaction between Fe* and NCS ions. The equilibrium constant for

Consider the reaction between Fe* and NCS ions. The equilibrium constant for this reaction is 620.4. Calculate the equilibrium concentration of NCS ion in a solution that contains 10.0mL of 0.05 M ferric nitrate in 1M HNO,, 2.0mL of 5.0x10 M NANCS, and 8.0mL of distilled water. Assume that all the NCS is converted to FeNCS+. (A) 6.07x10-8 M (B) 3.04 x10 M (C) 0 M (D) 1.00 x106
