Suppose the interaction between two atoms has the effective potential energy curve shown below:

I have marked the vertical scale on this graph using an arbitrary energy unit we'll call bondits.
-Suppose instead we know that at $t=0$ the atoms are at rest at a separation of $0.4 \mathrm{~nm}$. What minimum energy is required to break the bond in this case?

(If the system is at rest at r = 0.4 nm, then its total energy is zero. Increasing the
system's energy above the peak at r = 0.5 nm requires 5 bondits of energy.)
