Question

According to the collision theory, all collisions do NOT result in the desired product. Which two of the following gives both reasons why not all collisions between reactant molecules leads to the desired product?

1. The molecules don’t have enough kinetic energy 2. Solids cannot react with liquids or gases 3. Molecules cannot react with one another unless a catalyst is present 4. Molecules that are improperly oriented during collisions will not react

A. 1 and 2 .

B. 1 and 3 .

C. 1 and 4 .

D. 2 and 4 .

E. 3 and 4

Explanation / Answer

Ans: C. 1 and 4 .

Explanation: According to collision theory, the molecules which posses the activation energy only will undergo collisons as well as these molecules should be oriented in proper msnner to participate in collisons.

Remaining two options were not correct because solids can react with liquids and for all collisons catalyst is not required
