Question

Calculate the bond energy required to break the bond between atoms A and B in a molecule of AB, given the following information: the bond length between A and B is 0.1 nm and the energy required to break one mole of AB molecules is 500 kJ/mol.

Answer 1

To calculate the bond energy required to break the bond between atoms A and B in a molecule of AB, we can use the given information. We are given the energy required to break one mole of AB molecules, which is 500 kJ/mol. First, we need to convert the energy from kJ/mol to J/mol:500 kJ/mol * 1000 J/kJ = 500,000 J/molNow, we need to find the energy required to break a single AB molecule. To do this, we will divide the energy required to break one mole of AB molecules by Avogadro's number  6.022 x 10^23 molecules/mol :500,000 J/mol /  6.022 x 10^23 molecules/mol  = 8.31 x 10^-19 J/moleculeSo, the bond energy required to break the bond between atoms A and B in a single molecule of AB is 8.31 x 10^-19 J.
