Question

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

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

Reaction rates always increase as masses of solid reactants increase.

Concentrations of homogeneous catalysts have no effect on reaction rates.

Reaction rate constants decrease with increasing temperature.

Reaction rates can show little change as masses of solid reactants increase.

Slow reactions can be speeded up by raising the temperature.

The rate of a reaction is independent of temperature.

Explanation / Answer

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

Reaction rates can show little change as masses of solid reactants increase.

Slow reactions can be speeded up by raising the temperature.
