NEET Chemistry Chemical Kinetics Questions Solved


What is the activation energy for the decomposition of N2O5 as N2O5 2NO2+ (1/2) O2 If the values of the rate constants are 3.45×105 and 6.9×10-3 at 27°C and 67°C respectively.

(A) 102 ×102kJ                                      

(B) 488.5 kJ

(C) 112 kJ                                              

(D) 112.5 kJ

(D) logk2k1=Ea2.303RT2-T1T1T2log 6.9×10-33.45×10-5=Ea2.303×8.3140300×400Ea=112.5 KJ
