(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.

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

As a reaction progresses its rate goes down.

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

The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step.

Reaction rate constants increase with increasing temperature.

Fast reactions can be slowed down by lowering the temperature.

Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. If Q > K the reaction must progress backward to attain equilibrium. As a reaction progresses forward toward equilibrium K is the highest value Q attains. If Q < K the reaction must progress backwards to attain equilibrium. A reaction quotient is the same as an equilibrium constant. The further away from K the Q...
