The graph shows the potential energy of a system of two ions as a function of their interionic separtion. The system of the two icns has a total mechanical energy of `-0.5xx10^(-17)j.` What is the range of possible values for the distance between the two ions? At what separation do the ions have minimum kinetic energy? What is the maximum possible kinetic energy of the ions? what energy is required to breake apart this ionic molecule? |

Answer» (i) `1.7xx10^(-10)` m to `5.0xx10^(-10)m` (Outside this range the potential energy would need to be greater than the total energy, that is the kinetic energy would have to be negative which is an impossible situation) (ii) `1.7xx10^(-10)mor5.0xx10^(-10)m(K.E.=0)` (iii) `1.5xx10^(-7)J(at d=3.0xx10^(-10)m)` (iv) `0.5xx10^(-17)J.` (The total mechanical energy must be increased to 0) |
