Collision theory Quiz 2

chemistry

 There are two types of collisions, effective collisions, and ineffective collisions. The effective collisions are different from ineffective collisions because they have energy greater than:

  Some of the collisions have energy higher than the minimum energy for the reaction to occur.

The effective collisions are responsible for the formation of products because these collisions have higher energy than the threshold energy.

 Collision theory stated for an elementary molecular reaction, rate of the reaction is the product of collision frequency and effective collisions, when effective collision is equal to:

 According to the collision theory, the rate of reaction is given as:$Rate={{Z}_{AB}}{{e}^{-{{E}_{a}}/RT}}$

 According to the collision theory, the rate of reaction is given as:<br>$\\ Rate={{Z}_{AB}}{{e}^{-{{E}_{a}}/RT}} \\ {{Z}_{AB}}\text{ is the collision frequency and }{{e}^{-{{E}_{a}}/RT}}$ is the effective collision.

 According to the collision theory, the effective collision must be there and their orientation must be correct to form the product.

 According to the collision theory, the effective collision must be there, and their orientation must be correct, therefore, in case I, the orientation is correct for the formation of ${{N}_{2}}{{O}_{4}}$.

 The collision theory, the reaction rate depends on the number of effective collisions, so we can ______________ to increase the collisions.

 To increase the collisions of the reactant molecules, the kinetic energy of the molecules should be increased.

 To increase the collisions of the reactant molecules, the kinetic energy of the molecules should be increased, from the options given, increasing temperature can increase the collision.

 Collision theory was able to explain the Rate of reaction, but it was having limitation, that:

  This theory does not take the consideration of structural aspects.

 This theory assumed that the atoms are hard spheres and do not take the consideration of structural aspects which is the limitation of collision theory.
