(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 fastest step in a reaction is called the rate-determining step. 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. Catalysts increase reaction rates. Reaction rates increase as reactant concentrations decrease. Solid...

Which of the following statements about this graph are correct? Arrow A indicates the reaction at equilibrium because it shows the relative concentration of the reactants decreasing and the products increasing. Arrow B indicates the reaction at equilibrium because the relative concentrations of X and Y...

4. -10.1 points 0/4 Submissions Used (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 decrease with increasing temperature. Catalysts increase reaction rates. O Reaction rates can show little change as masses of solid reactants increase. Catalysts decrease reaction rates. Reaction rates increase as concentrations of homogeneous catalysts increase. Slow reactions can be speeded up by raising the temperature.
