RP3 - Effect of temperature on rate of a reaction

Question 1

How an rate of reaction be measured?

Answer 1

1. Initial rates method
2. A continuing monitoring method

Question 2

Why does rate of reaction increase with temperature?

Answer 2

1. As temperature increases, the kinetic energy of molecule also increases. This means more molecules have energy greater than the activation energy than can react

Question 3

In an experiment investigating the effect of temperature on rate of reaction, what variables will you control?

Answer 3

1. Concentration of reactants and products
2. Volumes of reactants and products
3. Use the same beaker and cross underneath it
4. Use the same person to decide when the cross has disappeared

Question 4

How do you keep a substance at a constant temperature?

Answer 4

1. Use a water bath
