The open shell molecules with even number of electrons have $\pi^2$ or $\pi^{2}_{g}$ ground-state electronic configuration. Several homonuclear diatomic molecules like $\rm{O_2, S_2, B_2}$ have $\pi^{2}_{g}$ ground state in the $D_{\infty h}$ point group and heteronuclear diatomic radicals like PH, NH, SO have $\pi^2$ ground state in the $C_{\infty v}$ point group. We have computed and presented here the rate coefficient of these open shell molecules $\rm{(O_2, S_2, B_2)}$ and radicals (PH, NH,SO) from the results of our previous studies using a well-established $\it {ab-initio}$ formalism: the $R$-matrix method. The rate coefficients for elastic and electron-excited processes are studied over a wide electron temperature range.
