11. In a research project, a scientist adds 0.1 mole of HCN, 0.1 mole of H;O*, and 0.1 mole of CN to water to make a total volume of 1 L. Will this reaction proceed to a greater extent in the forward direction or in the reverse direction? HCN + H,O H;0+ + CN¯ Ka = 6.2 × 10-10 %3D (A) Forward; acids always dissociate in water. (B) Forward; the K value is less than 1. (C) Reverse; the K value is less than 1. (D) Reverse; water cannot be a reactant.

#11 please. We get K equals one. Can We see your approach? See pics .This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl
