WebSelect the single best answer. Ea = 30 kJ/mol or Ea = 3 kJ/mol. Ea = 3 kJ/mol. For a reaction with ΔH° = −6 kJ/mol, decide if the following statement is true. The reaction is … WebJul 19, 2024 · If the temperature is higher, the reactant molecules have a higher kinetic energy, and thus the energy difference between the threshold energy and the energy of the molecules will decrease, that is, the activation energy will decrease. physical-chemistry kinetics energy Share Improve this question edited Jul 19, 2024 at 16:37 Mithoron
WebActivation energy and heat of reaction in a reaction system. If the same reaction is studied with different catalysts or if analogous reactions are compared, it is usually found that the quantities Eact and A of the Arrhenius equations are interrelated. An increase in Eact is then “compensated” by an increase in A according to the equation: (20.10)
WebThe activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because … how do you find megalopolises areas on a mapWebWhen a reaction system is at equilibrium, it is in its lowest-energy state possible (has the least possible free energy). If a reaction is not at equilibrium, it will move spontaneously towards equilibrium, because this … how do you find metsWebA low activation energy means that a lot of the particles will collide with enough energy to react.
