    The stability order of carbocation is tertiary > secondary > primary . Now, both ethyl carbocation and n-propyl carbocation are primary carbocation . Yet , n-propyl carbocation is more stable than ethyl carbocation . Because , +I effect of ethyl group is slightly higher than +I effect of methyl group. In terms of hyperconjugation, ethyl carbocation is more stable than propyl carbocation but when thermodynamic stability, heat of formation data etc supports for the stability of propyl carbocation over ethyl carbocation.
