What is the K for the reaction 2Cu(s)+O2(g)2CuO(s) equivalent to? A) (Kl)(K2) B) (Kl)+(K2) C) [(Kl)(K2)]1/2 D) [K2K1]1/2 E) 2[(K1)(K2)] F) 2[(K1)2+(K2)] 5. (6 points) Consider the dissolution of an ionic solid that is soluble in water and has Hsolution=22.6kJ/mol and Hhydration=797.4kJ/mol. The lattice energy for this solid would be . kJ/mol, the change in entropy would be (+ or ), the free energy change would be (+ or ), and the ion-dipole forces between the solute particles and water are (larger/smaller) in magnitude than the sum of Hsolute+Hsolvent
