Solution: Indicate whether the following statements are true (T) or false (F):___ The higher the activation energy, the slower a reaction at a given temperature.___ A homogenous catalyst is present in the same phase as the reacting molecules.___ Most reactions occur by a one-step mechanism.___ A unimolecular elementary step involves only a single reactant that breaks apart.___ Termolecular reactions require that three molecules collide simultaneously.___ The half-life of a first-order reaction is constant.___ As the temperature is increased, the number of species reaching the transition state of the rate-determining step increases.
