Following are the values of `E_(a)` and `DeltaH` for three reactions carried out at the same temperature :
`I : E_(a) =20 kJ mol^(-1), DeltaH =-60 k J mol^(-1)`
II : `E_(a)=10 kJ mol^(-1), DeltaH =-20 kJ mol^(-1)`
III: `E_(a) =40 kJ mol^(-1) , DeltaH =+15 kJ mol^(-1)`
If all the three reaction have same frequency factor then fastest and slowest reations are :

Options

A. `{:("Fastest",,"Slowest"),(I,,II):}`
B. `{:("Fastest",,"Slowest"),(II,,III):}`
C. `{:("Fastest",,"Slowest"),(I,,III):}`
D. can't be predicted

Answer

B
