How can the speed of solvent molecules be slowed down? OA. by increasing the temperature
OB. by increasing the surface area of the solute
OC. by increasing the pressure
OD. by decreasing the temperature
O E. by decreasing the surface area of the solute

All of the following are part of the biosphere except

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.
