Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The tme for which the oxygen atom remains adsorbed on a tungsten surface is 0.36sat 2550 K. and 3.49 at 2360 K. Caleulate the activation energy of desorption of oxygen atom. Atom, assuming that the oxygen atoms is tightly chemisorbed, calculate the pre-exponential factor t in the Arrhenius- type expression. .

for first part check this

Activation energy of desorption of oxygen atom

thn how will calculate pre exponential factor ?
![eduncle-logo-app]()
as it is asked to find pre exponential factor from arrhenius type equation... So using equation K=A e^-Ea/RT... where A= pre exponential factor
![eduncle-logo-app]()
average life is given as desorption in typically first order reaction so tavg=1.44 t1/2 and t1/2=0.693/k...from there you find k and Ea activation energy is calculated in first part...then you calculate pre exponential factor

got this shristy.?
