On the basis of Arrhenius equation, consider the following statement (s)
I. `E_(a)` is activation energy.
II. Unit of `E_(a) is j mol^(-1)`
III. R is gas constant.
Which of these is/are true statement(s)?

Options

A. I and II
B. II and III
C. I and III
D. I,II and III

Answer

D

Explanation

Arrhenius equation is ,
`k=Ae^(E_a//RT)`
where `E_(a)= " Activation energy " =J "mol"^(-1)`
R=Gas constant,T-Temperature So, all statements are correct.
