@Bajwa.
More corrosive fluids are passed through the tubes. Also, the fluid with the greatest fouling tendency is usually passed through the tubes where cleaning is easier.

Counter flow because aqueous solution outlet temp can be greater than the steam outlet temp and also shell side because the presence of baffles increases the velocity of the aqueous solution, and the higher the velocity, the more heat gained by the aqueous solution.
