Why does stirring increase the rate of dissolution?
gavmur [86]

The correct option is D.

When dissolving a substance in a solvent, stirring the solution will increased the rate at which the substance dissolved. This is because, when one stirs a solution, it exposes more surface area of the solute to the solvent, thus, increasing the interaction between the solute and the solvent. The higher the quantity of the solute that is exposed to the solvent, the higher the rate of dissolution of the solute.

Delvig [45]

Answer:

0.225 atm

p1v1=p2v2

p2=p1v1/v2

=1×0.45/2
