Greetings,
I'm trying to get an intuitive understanding about a process involving an ion mobility that (I'm told) has D = 9.3 x 10-5 cm2/s. I'm assuming that D is a diffusion coefficient.
I'd like to know approximately how long it takes for the ion to travel about 10 cm. Would this be something that happens in a matter of femtoseconds, minutes, hours, weeks, years... or what? Unfortunately I don't have any more information than that, so is there some way to calculate (or just roughly guess) the ion speed based on D?
many thanks,
Mark
