NEET Chemistry Chemical Kinetics Questions Solved


When temperature is increased from 27°C to 127°C, rate of reaction becomes doubled, then Ea will be?

1. 1.66 KCal.

2. 3.32 KCal.

3. 5.33 KCal.

4. 6.64 KCal.

(1) log k1/k2 = Ea/2.303R[T2-T1/T1T2]

     log2 = Ea/2.303x2x10-3 x 100/300x400

     Ea = 1.66 Kcal.
