Rate of reaction

The video explains how to measure reaction rates by assessing the amount of reactant used or product formed over time. It also discusses factors that can influence the speed of reactions, such as temperature, concentration, pressure, and catalysts.

How can the rate of a chemical reaction be determined?

• By observing the color change

• By measuring the amount of reactant used or product formed

• By measuring the temperature change

• By calculating the pH level

What is one way to measure the progress of a chemical reaction?

• By calculating the density

• By observing the light intensity

• By measuring the amount of product formed

• By checking the pressure

Which of the following is NOT a factor that affects the speed of a chemical reaction?

• Pressure

• Temperature

• Concentration

• Color

What role does a catalyst play in a chemical reaction?

• It increases the temperature

• It decreases the concentration

• It speeds up the reaction

• It changes the color of the reactants

Which factor can slow down a chemical reaction?

• Increasing pressure

• Adding a catalyst

• Increasing temperature

• Decreasing concentration
