Answer:
value for any metal
is the sum of enthalpy changes taking place in the steps given below :
(is
standard enthalpy of atomisation)
M(g) +
(is
standard ionisation enthalpy)
M2+(g) +
aqM2+(aq)
+
(is
standard hydration enthalpy)
Copper has high
enthalpy of ionisation (energy absorbed) but low enthalpy of hydration (energy
released). Thus is positive.
