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 :
