Chemical Kinetics -- Help me with this question ( detailed
answer please )
If enthalpy for absorption of ammonia on a metal surface is
-85kJ / mol, and the residence time on the surface at room
temperature is 412 s estimate the residence time of an NH3 molecule
on the surface at 300 ° C.
Relationships: Arrhenius eqation : K(disorption) =
Ae-deltaEd /RT ... Half time t = 0.693/
K(disorption)... delta Ed = 100 kJ/mol. This is a first
order kinetic reaction.
The correct answer should be 29 μs.
