What happens to the rate of reaction if the pressure of gases is INCREASED?Reaction stopsRate of reaction decreasesRate of reaction increasesRate of reaction is unaffectedQuestion 1 of 15 Loading... 2. On a graph showing gas produced (vertical axis) over time (horizontal axis), how does the line tell us the rate of reaction?The steeper the line, the faster the rate of reactionThe longer the line, the slower the rate of reactionThe longer the line, the faster the rate of reactionThe steeper the line, the slower the rate of reactionQuestion 2 of 15 Loading... 3.

Describe the laboratory preparation of oxygen from hydrogen peroxideHydrogen peroxide is added to a flask containing a catalyst of magnesium oxide, MgO₂. Oxygen is produced and is collected underwater.Hydrogen peroxide is added to a flask containing a catalyst of nickel oxide, NiO₃. Oxygen is produced and is collected underwater.Hydrogen peroxide is added to a flask containing a catalyst of manganese oxide, MnO₂. Oxygen is produced and is collected underwater.Hydrogen peroxide is added to a flask containing a catalyst of vanadium oxide, V₂O₅.

Explain how a catalyst worksA catalyst increases the surface area of the reagents to increase the rate of reactionA catalyst increases the concentration of the reagents by taking up water to increase the rate of reactionA catalyst reduces the activation energy of the reactionA catalyst provides an alternative pathway with lower activation energyQuestion 9 of 15 Loading... 10. Hydrochloric acid reacts with an excess of calcum carbonate in a flask. The volume of carbon dioxide given off is measured in a gas syringe. This is shown on the graph. How would the graph look different if the reaction was done with the same volume of acid, but with an acid which is twice as concentrated?The line would rise more steeply, and finish at a higher level than the original, but how much higher would depend on whether the calcium carbonate were still in excess.The line would rise at the same rate, but finish at twice the height of the original.No change. Line would look the same.The line would rise more steeply, and finish at a twice the height of the original.Question 10 of 15 Loading... 11. Explain the effects of increasing the temperature on the rate of a reaction in terms of particle collision theory1) particles have more kinetic energy 2) more frequent collisions 3) and a lower proportion of the collisions which occur have greater or equal to the activitation energy 4) increase rate of reaction1) particles have more kinetic energy 2) more frequent collisions 3) and a higher proportion of the collisions which occur have greater or equal to the activation energy 4) increase rate of reaction1) particles have less kinetic energy 2) less frequent collisions 3) and a lower proportion of the collisions which occur have greater or equal to the activitation energy 4) decrease rate of reaction1) particles have less kinetic energy 2) less frequent collisions 3) and a lower proportion of the collisions which occur have greater or equal to the activitation energy 4) increase rate of reactionQuestion 11 of 15 Loading... 12. What happens if two particles collide with less than the activation energyNo reactionThe reaction still occurs but very slowlyThe particles fuse togetherThe reaction only goes partwayQuestion 12 of 15 Loading... 13. Explain the effects of increasing the surface area of a solid on the rate of a reaction in terms of particle collision theory1) more particles exposed 2) more frequent collisions 3) increase rate of reaction1) more particles exposed 2) less frequent collisions 3) decrease rate of reaction1) more particles exposed 2) less frequent collisions 3) increase rate of reaction1) more particles exposed 2) more frequent collisions 3) decrease rate of reactionQuestion 13 of 15 Loading... 14. Large chips of calcium carbonate reacts with an excess of hydrochloric acid in a flask. The volume of carbon dioxide given off is measured in a gas syringe. This is shown on the graph. How would the graph look different if the reaction was done with a powdered calcium carbonate?Line rises more steeply. Levels out at higher level.Line rises more steeply. Levels out at same level.Line rises less steeply. Levels out at lower level.Line rises at same rate, but levels out at a higher level.Question 14 of 15 Loading... 15.
