In the present work electron impact excitation rate coefficients of laser states by the processes like electron impact excitation, Penning excitation and Duffenduck reaction are obtained as a function of electron temperature. The electron impact excitation rate coefficient of the laser states of CdII from the ground state of CdI and CdII are obtained by considering the equation of electron The Penning excitation and Duffenduck reaction rate both increase as the gas temperature is increased. The rate coefficients of both processes are proportional to the square root of gas temperature. Gas temperature determines the collision frequency and hence the rate coefficient.
