Homework Answers
The correct statements among the given statements are -
1) The lower the rate of a reaction the longer it takes to reach completion.
2) Catalysts increase reaction rates as catalysts direct the same reaction to proceed in an alternative pathway where the activation energy is lower than the earlier pathway without catalysts.
3) Reaction rates increases as concentrations of homogeneous catalysts increases.
4) Slow reactions can be speeded up by raising the temperature because with increasing temperature the number of collisions among the reactants increases which leads to the increase in the reaction rate.

(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. Solid catalysts increase reaction rates as their surface areas increase. The slowest step in a reaction is called the rate-determining step. Catalysts increase reaction rates. The rate of a reaction is the same as the rate constant of the reaction. Reaction rates increase as concentrations of homogeneous catalysts increase. Reaction rates decrease...

(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. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. As a reaction progresses its rate goes down. Concentrations of homogeneous catalysts have no effect on reaction rates. Reaction rates always increase as masses of solid reactants increase. The fastest step...

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the product concentrations rise. At equilibrium concentrations of reactants and products stay constant. At equilibrium there are always equal amounts of reactants and products.
