Iron has higher enthalpy of atomisation
WebDec 22, 2024 · Iron has a higher enthalpy of atomization than copper because of the number of electrons present in its d- orbitals. Electronic configuration of Iron- 3d64s2 … WebMar 19, 2024 · I will quote but a small summary part of the results relating to acidic conditions: As the pH decreases, the solution is more acidic, so 10−pH= [H+] increases and 10pH−14= [OH−] decreases. If H+ is a product, Q therefore increases, and the nonstandard cell potential decreases.
