(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. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. Catalysts increase reaction rates Reaction rates are determined by reactant concentrations, temperatures, and reactant stabilities Reaction rates increase with increasing temperature Reaction rate constants decrease with increasing temperature. Reaction rate constants increase with increasing temperature
