The graph below shows the change in potential energy that takes place as the distance
between the two hydrogen(H) nuclei changes leading to
formation of hydrogen
molecule(Ha) The Points W X Y and Z represent
the different positions of the atoms
Potential energy kJ mo
0,08
W
Distance between nuclei (pm)
31 Define the term bond length
3.2 From the graph, write down the
3.2.1 Value of the bond energy
3.2.2 Value of the bond length.
3.2.3 Position W. X. Y or Z where H2 molecule is formed.
3.2.4 Position W, X, Y or Z where H2 molecule formed is most unstable.
Explain the answer.
How does the repulsive force between
