Question

Can someone explain please?
If an elementary reaction involves the collision of two identical molecules, then the elementary reaction is _____, and the kinetics will be ______.
A) unimolecular, second-order
B) bimolecular, first-order
C) bimolecular, second-order
D) unimolecular, zeroth-order
E) unimolecualr, first-order

Answer 1

bi molecular and second order

Answer 2

Thank you! Could you explain why that is, please? :)

Answer 3

since two molecules are involved in this we can say it as bi molecular
but it is difficult to tell the order bcoz it has to be determined experimentally
but still we can predict
according to rate equation
R=K[A]2

Answer 4

Thank you!
