Chemical Kinetics

It is the factor that affect affection rates where reactants must come together to react.

One of the factors that affect reactions rate where most chemical reactions proceed faster if the concentration of one or more reactants is increased.

Reaction rates generally decrease as temperature is increased.

• True

• False

Catalysts are agents that increase reaction rates without themselves being used up.

• True

• False

The following are the kinds of intermolecular interactions are involved in solution formation EXCEPT:

• Solute–solute

• Solvent–solvent

• Solvent–solute

• Solution-solvent

Is it possible for all phases of matter to be a solvent? Why? why not?

A solution that is in equilibrium with undissolved solute is saturated.

• True

• False

The amount of solute needed to form a saturated solution in a given quantity of solvent is known as the solubility of that solvent.

• True

• False

If we dissolve less solute than the amount needed to form a saturated solution, the solution is unsaturated.

• True

• False

Under suitable conditions it is possible to form solutions that contain a greater amount of solvent than needed to form a saturated solution. Such solutions are supersaturated.

• True

• False
