Answer

Explanation:

Step1: Observe at 0°C

At 0°C, the molecules move relatively slowly. They have less kinetic - energy, resulting in fewer and less energetic collisions.

Step2: Observe at 200°C

When the temperature is increased to 200°C, the molecules move much more rapidly. The increased kinetic energy leads to more frequent and more energetic collisions.

Step3: Analyze chemical reaction at higher temperature

At the higher temperature (200°C), the chemical reaction occurs more quickly. The increased frequency and energy of collisions mean more reactant molecules have enough energy to form the activated complex and proceed to form products.

Answer:

A. At 0°C, the molecules move slowly with less frequent and less energetic collisions. B. Increasing the temperature to 200°C makes the molecules move much more rapidly, with more frequent and more energetic collisions. C. The chemical reaction occurs more quickly at the higher temperature due to more frequent and energetic collisions allowing more reactants to form products.
