Year 11 Chemistry Spring 3 Quiz 7- C8 Rates & Equilibrium Pt 1

C8.1 What is meant by the phrase 'rate of reaction'?

• How much product is made

• How quickly a chemical reaction occurs

• How much reactant is used up

• How far a chemical reaction goes

C8.1 Which of these is NOT a valid way of measuring the rate of reaction?

• The change in mass of a reaction over time

• What volume of gas is produced over time

• How long it takes a colour change to occur

• The highest temperature recorded in a chemical reaction

C8.1 Which piece of equipment would you use to measure the volume of a liquid?

• Gas syringe

• Beaker

• Conical flask

• Measuring cylinder

C8.1 Which piece of equipment could you NOT use to measure the volume of gas produced by a reaction over time

• Inverted Beaker

• Inverted burette

• Inverted measuring cylinder

• Gas syringe

C8.1 What does 'control variable' mean?

• The thing you change

• The thing you measure

• The thing you keep the same

• The thing you ignore

C8.1 If you were measuring how the concentration of an acid affected the rate at which it reacts with a piece of magnesium metal, which of these is NOT an appropriate control variable

• The mass of magnesium

• The volume of acid

• The temperature of the acid

• The volume of the container used

C8.1 Which of these would NOT affect the rate of a chemical reaction?

• Temperature of the reaction mixture

• Volume of the reaction mixture

• The concentration of any solutions used

• The surface area of any solids used

C8.1 What is this piece of equipment called?

• Beaker

• Conical flask

• Measuring cylinder

• Jar

C8.1 How can you tell this reaction went quickest at the start of the reaction?

• Because the line goes up

• Because the line in a curve

• Because the gradient is steepest

• Because the line levels out

C8.1 Which line represents the experiment where a greater mass of marble chips was used?

• Blue

• Green

• Orange

• Purple
