Question

Select all of the correct statements about reaction rates from the choices below.

1

The lower the rate of a reaction the longer it takes to reach completion.


Reaction rates increase as concentrations of homogeneous catalysts increase.


Solid catalysts do not affect reaction rates.


Catalysts decrease reaction rates.


Reaction rate constants decrease with increasing temperature.


A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant.


Reactions involving very unstable combinations of chemicals have large rate constants.

Explanation / Answer

1. correct
2. correct
3. correct
4. false
5. correct
6. false
7.correct


Rate of reaction are dependent on the temperature, some times pressure(if gases involved), size of particles (smaller goes faster) concentration of reactants, and in reversible reactions concentration of products.and presence of a catalyst which is not used up
