Folowing are the values of E, and AH for three reactons carmed out at the same tenypera :E-20 k mol, AH--60 kJ mo II:E-10k mo, AH-20kJ mol I: E=40 ki mol,AH=+15 kJ mo 84 lf all the three reaction have same frequency factor then tastest and slowest reacthons are Fastest Slowest (a) I (b) II II (c) I (d) can't be predicted.
Since delta H is a thermodynamic parameter ,not a kinetic parameter. So it has no role in deciding the rate of reaction.
Now,from Arrhenius equation we can see that rate constan...
