I have this solution that I don't quite understand
d(ro*pi*D^3/6)/d(t)=-kr*Cao*pi*D^2
from here I would have thought to separate the variables and integrate but the solution says
ro/2* d(D)/d(t) = -kr Cao
I guess my question is how are you able to do that? If you take the derivative of D, why is d(D)/d(t) still left behind?
