Question

Two molecules collide and a reaction not occur. Which of the following is not a valid explanation for this?

• A. The molecules were not in the proper states of matter.
• B. The molecules did not have enough kinetic energy.
• C. The molecules were not oriented correctly when they struck each other.
• D. The temperature of the reaction mixture was not high enough.

Answer 1

The correct option is A The molecules were not in the proper states of matter.

For a reaction to occur,

$\left(i\right)$The two molecules must collide with proper orientation.

$\left(ii\right)$They should have high kinetic energy.

$\left(iii\right)$ The temperature should be high.

$\left(iv\right)$But the state of matter does not have any effect on the reaction.

The states of matter molecules do not affect the rate of reaction.
