Question

Arrhenius equation is:

• A. $ \Delta H=\Delta E+\Delta {{n}_{g}}RT $
• B. $ \Delta G=\Delta H-T.\Delta S $
• C. $ K=A{{e}^{-{{E}_{a}}/RT}} $
• D. none of the above

Answer 1

Answer: (C)

Arrhenius equation gives relation between rate constant and temperature of a reaction. It can be written in many forms, as
$ k=A{{e}^{-{{E}_{a}}/RT}} $
where, k = rate constant
$ {{E}_{a}}= $ activation energy
$ T= $ absolute temperature
$ A= $ frequency factor
