Web7. The solubility of Group 2 sulphates decreases down the group. REASON: Both enthalpy change of lattice and enthalpy change of hydration are involved. Enthalpy change of hydration decreases more than enthalpy change of lattice. So, enthalpy change of solution becomes more endothermic. Please explain the text in bold.

Lattice energy (numerical value) of chloride of alkali metals is in ...
Webb) The lattice enthalpy for strontium chloride is greater than RbCl because: \n \n; Rb + has a larger ionic radius than Sr 2+ AND Rb + has a 1+ charge and Sr 2+ has a 2+ charge; [1] \n; The bond between Rb ion and C l ion is therefore weaker than the bond between the Sr ion and C l-ion; [1] \n \n [Total: 2 marks] \n \n WebNov 23, 2024 · Based on lattice enthalpy and other considerations which one the following alkali metals chlorides is expected to have the higher melting point? (a) RbCl (b) KCl (c ... Answer: (c) NaCl Explanation: The highest melting point will be NaCl, it is because, the lattice energy decreases as the size of alkali metal increases so going ... bkc tk122 angler 12-foot 8 inch tandem review

WebDec 2, 2024 · The enthalpy of formation of CsCl is -311 kJ/mol.. We have the following information from the question; Lattice energy (ΔH lattice) = − 657 kJ/molHeat of sublimation of Cs ( ΔH sub) = 76.5 kJ/mol Ionization energy of Cs (IE) = 376 kJ/molBond energy of Cl2 (BE) = 243 kJ/molElectron affinity of C l(EA) = − 349 kJ/molUsing Hess law of constant … WebThe energy required to separate the ions in a crystal lattice into individual gaseous ions is known as lattice energy. Lattice energy depends on the strength of interactions between cations and anions in the lattice, which we can estimate using Coulomb's law: Fₑ = (q₁q₂)/r².According to this equation, stronger interactions occur between ions with larger … Web2 answers. #1 is a little confusing with the use of the word largest. I think it is common practice to list LiF as the largest lattice energy but technically it is the smallest number. Lattice energies are as follows: LiF = -1036 kJ/mol. NaF = -923 kJ/mol. LiCl = -853 kJ/mol. NaCl = -787 kJ/mol. Therefore, I think you answer to #1 is ok but do ... bkc tk122 angler 12-foot 8 inch tandem
