It is known that a molecule at $25$C carries out an average displacement of $0\mathrm{.}067$ cm$.$ at $20$ seconds. At $110$C and $1$ atm. of pressure, calculate its diffusion coefficient and its average displacement in $14$ seconds.

Data: the viscosity of water at $25$oC is $0\mathrm{.}894$x$10-2$ g$$s$-1$cm$-1.$ Approximate its collision area to that of a circle.
