Rate of a general reaction 
Products can be expressed as follows on the basis of
collision theory. 
Which of the following statement is not correct for the above expression?
A
Z is collision frequency and is equal to number of collisions per second per unit volume of the reaction mixture
B
is the fraction of molecules with kinetic energy equal to or greater than 
.
C
is activation energy of the reaction
D
All the molecules which colloid with one other are effective collisions
Text Solution
Verified by ExpertsThe correct answer is:
D
Only those collisions in which molecules collide with sufficient energy and proper orientation are effective collisions. Rest of the molecule collides and bounce back.
