(a) Select all of the correct statements about reaction rates from the choices below: The lower the rate of a resction the longer it takes to reach completion. Sold catalyits do not affect reaction rates. Reaction rate toristants decresse with increasing temperature. fieactions invelving very unstable combinations of chemicals have large rate constants. The rate af a reoction is independent of temperature. Catalysts increase reactien rates. The somest step in a reaction is called the rate determining step
