Question

Chemistry Question on Rate of a Chemical Reaction

The Arrhenius equation expressing the effect of temperature on the rate constant of a reaction is

A

k=e−E/RTk=e^{-E / R T}

B

k=ln⁡ERTk=\ln \frac{E}{R T}

C

k=A.ERTk=\frac{A . E}{R T}

D

k=A.e−Ea/RTk=A . e^{-E_{a} / R T}

Answer

k=A.e−Ea/RTk=A . e^{-E_{a} / R T}

Explanation

Solution

Arrhenius proposed a quantitative relationship between the rate constant and temperature as: k=Ae−Ea/RTk=A e^{-E_{a} / R T}
where, AA = frequency factor
Ea=E_{a}= activation energy
