17 мар. 2018 г. · Re: What are the units of activation energy? You use J/mol. Look at the Arrhenius equation, k = A*e^(-Ea/RT). R has units of J*K-1*mol-1 while ...

12 мар. 2020 г. · The units for activation energy are joules/mol. Joules gives the energy and the moles makes it standard for the reaction.

11 мар. 2021 г. · The units are kJ/mol or J/mol. Make sure to account for which one to use by checking the units of the other values in the equation you plug it into.

8 мар. 2021 г. · The activation energy problems will most of the time be given in kJ. However, the Arrhenius equation uses Joules, so make sure to convert from kj to Joules.

16 мар. 2019 г. · The units for Ea are J/mol or kJ/mol etc. What is the /mol referring to? Is it per mole of product? What if 2 products are made?

14 мар. 2023 г. · In the Arrhenius equation, the units of activation energy (J/mol), R (J/mol/K), and temperature (K) cancel out, leaving the exponential unitless ...

18 мар. 2023 г. · Activation energy, Ea, is the amount of energy required to be overcome before any reaction can take place, regardless of whether the ...

14 мар. 2020 г. · The activation energy of a reaction is measured in joules (J), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).

19 мар. 2023 г. · Since we are given activation energies, we can use the equation k= A*e^(-Ea/ RT).

19 мар. 2024 г. · Activation energy is the energy barrier that must be overcame in order for a chemical reaction to occur.
