Web7. Given that the energy change when a carbon to carbon single bond is broken is +346 kJ, what is the enthalpy change when a carbon to carbon single bond is formed from two separate atoms? 346 kJ ... Web(a) (i) I-I bond is weaker/has a lower bond enthalpy value (so will break more easily) OR I 2-(151 kJ mol 1) is less than H 2 (436 kJ mol-1), (so will break more easily). 1 Iodine on its own is not acceptable. (ii) Peak of curve should be further to the right and no higher than the original line. 1 (iii) (A) Equilibrium will shift to the reactant WebTo learn more about how to calculate the energy needed to break bonds, review the corresponding lesson on Bond Enthalpy: Definition, Calculations & Values.
