Define : (a) Enthalpy of atomization (b) Lactic enthalpy. |
|
Answer» Solution :Enthalpy of atomization : It is defined as the enthalpy change accompanying the breaking of one mole of a SUBSTANCE completely into its atoms in the GAS phase. `H_(2)(g) rarr 2H(g) , Delta_(s)H^(@) = 435.0 kJ mol^(-1)` LATTICE enthalpy : It is the enthalpy change which occurs when one mole of an IONIC compound dissociates into its gaseous ionic state. `NaCl(s) rarr Na^(+) (g) + Cl^(-) (g) , Delta H = +788 ks//mol`. |
