When an energetic electron with the velocity of 1.00 x 106 m s-1 was collided with Rb atom (assume stationary), Rb- anion moves at 313 m s-1 and released 382.4 nm of visible light. Calculate the energy change during the formation of Rb- anion from Rb atom in kJ mol-1

Solutions

Expert Solution

The negative sign of change in energy means the Addition of one electron to Rb atom will generate interaction energy with other elements which will help in creating Rb- so change in energy is the interaction energy of electrons due to additional energy.
