Please answer 4,5,6 statement only

Choose the best answer below. Consider the following complex ion formation equilibrium and it's equilibrium constant, Kf. Which of the following statements is FALSE? Cu2+ (aq) + 4CN" (aq) Û Cu(CN)4²- (aq) Kf = 1.0x1025 O Adding more CN¯ will cause more complex ion to form The equilibrium lies in favor of the complex ion Cu2+ is a Lewis acid in the reaction, and CN- is a Lewis base Removing some of the Cu2* (e.g., by precipitation) will cause some of the complex ion to dissociate The complex ion is a Lewis acid-base adduct O If enough CN" is added, the equilibrium mixture would contain zero Cu2+
