Question

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

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


b) Fast reactions can be slowed down by lowering the temperature.


c) Reaction rate constants increase with increasing temperature.


d) The fastest step in a reaction is called the rate-determining step.


e) Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities.


f) The rate of a reaction is independent of temperature.


g) Reaction rates increase with increasing temperature.

Answer 1

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

The reaction will proceed according to rate constant which is quite low then reactants also will be consumed slowed. Hence it will long time.

b) Fast reactions can be slowed down by lowering the temperature.

Since temperature also one of the fact in determining the rate of reaction, when we lower the tempeature rate also will be decreased to go the reaction slow

c) Reaction rate constants increase with increasing temperature.

As above said point reversly can be taken. Tempeature is directly propotional to rate constant which increases with temperature .

e) Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities.

These 3 factors are determining the rate of the reaction

d & f are false ststements
