WebIt means that per mole water splitting requires at least 241.8 k J of energy. Any method (thermal,electrolysis etc) followed, this much of energy will be always required. When using electrolysis, it may be convenient to express it in e V. Regarding calculation, I have to mention that Δ H f ∘ s are experimental values. WebBromine and chlorine are halogens -- very reactive non-metals. Both bond to a variety of elements. Though chemically similar, their bond energy and resultant bond strength and stability are different. Stronger bonds are shorter bonds. Bond energy is the energy it takes to break the bond.
