Chemical Reaction Measurement and Collision Theory

Front

Identify two ways to measure the rate of this reaction between hydrogen and oxygen.

Back

1. Measure the volume of gas produced over time. 2. Measure the decrease in concentration of reactants over time.

Front

Describe a successful collision by crossing out the incorrect words in the paragraph.

Back

A successful collision occurs when particles collide with both the correct orientation and high enough energy, or speed, to form or break their bonds. If both conditions aren’t met, then the particles will collide with each other without reacting. The higher the frequency of successful collisions the higher the reaction rate.

Front

Draw the reaction of two hydrogen molecules (H₂) and one oxygen molecule (O₂) to form two water molecules (H₂O) at the particle level.

Back

Demonstrate a successful collision vs. an unsuccessful collision.

Front

Expert study tip: Draw it out

Back

Each choice you make in a drawing forces you to identify the most important ideas and how best to represent them. Then, while you draw, your brain has time to think about what you are drawing and make connections with what you already know.

Front

Learning goal 1

Back

I can define reaction rate.

Front

Learning goal 2

Back

I can recognize that reactant particles need to collide in order for a reaction to occur.
