Question

Collision theory demands knowing the fraction of molecular collisions having at least the kinetic energy Ea along the line of flight what is this fraction when
(a) Ea= 15 k] mol-1,
(b) Ea = 150 k] mol-1 at (i) 300 K and
(ii) 800 K?

David · Accepted Answer

K
2
= pAe-Ea/RT2
Answers:-
(a). E
a
= 15 kJ mol-1 = 15000 J mol-1
(i) T
1
=300 K
(ii) T
2
 = 800 K
We have to calculate the fraction of molecular collisions which is also called the
steric factor , p and the exponential factor ,
