Collision Theory and Reaction Rates

The video explains how sugar dissolves faster in hot water due to increased reaction rates, introducing Collision Theory by Max Trautz and William Lewis. It covers the necessity of particle collisions, sufficient energy, and correct orientation for reactions. The video concludes with a summary of these key ideas and a call to action.

What happens to sugar cubes when added to hot and cold water?

• They dissolve faster in hot water.

• They do not dissolve in either.

• They dissolve faster in cold water.

• They dissolve at the same rate.

Who developed the Collision Theory?

• Albert Einstein and Niels Bohr

• Marie Curie and Louis Pasteur

• Max Trautz and William Lewis

• Isaac Newton and Galileo Galilei

According to Collision Theory, what must particles do to react?

• Be stationary

• Be at absolute zero temperature

• Collide with each other

• Be in a vacuum

What analogy is used to describe particle collisions?

• Cars in a traffic jam

• Birds flying in formation

• Billiard balls in a pool game

• Dominoes falling

What is the minimum energy required for a reaction to occur called?

• Activation energy

• Thermal energy

• Kinetic energy

• Potential energy

How does temperature affect reaction rates?

• It increases the reaction rate.

• It decreases the reaction rate.

• It has no effect on the reaction rate.

• It stops the reaction completely.

What additional factor is crucial for some reactions besides collision and energy?

• Color

• Orientation

• Pressure

• Volume

In the example of Nitrogen monoxide and ozone, why did the reaction not occur initially?

• The molecules were moving too slowly.

• The molecules were at the wrong temperature.

• The molecules were too far apart.

• The oxygen atoms of each molecule touched.

What are the three key ideas of Collision Theory?

• Distance, time, and speed

• Mass, velocity, and acceleration

• Pressure, volume, and temperature

• Collision, energy, and orientation
