NEET Chemistry Chemical Kinetics Questions Solved


The rate of reaction triples when temperature change from 20°C to 50°C. Calculate energy of activation for the reaction.

(A)28.81 kJ mol-1                                         

(B)  38.51 kJ mol-1

(C) 18.81 kJ mol-1 

D 8.31 kJ mol-1

(A) The Arrhenious eq. is

 ln k2k1=EaRT2-T1T1T2given k2k1=3

now ln3=Ea8.314×323-293323×293Ea=28.81 kJ mol-1
