How to calculate bond energy change
Web21 okt. 2024 · Calculate the energy change = energy in – energy out. The bond energy of a molecule is the enthalpy change when one mole of a mole of gaseous molecules dissociates into its atomic constituents. Bond Energy = Energy needed to break 1 mol of a particular type of bond between atoms of the same element in their gaseous state. WebThe required energy to break a C=0 bond is 749kj/mol and the energy to break an H-O bond is 428kj/mol, so in order to form those bonds we have to add a - for each of those values. That means we will have to release …
