What happens to the rate of reaction if the pressure of gases is INCREASED?Rate of reaction decreasesReaction stopsRate of reaction is unaffectedRate of reaction increasesQuestion 4 of 15 Loading... 5. What is meant by the term activation energy?The energy released by the reactionThe maximum energy of the final product for it to be stableThe minimum energy that the particles in collision must have if a reaction is going to occurThe energy provided by the catalyst to allow a reaction to proceedQuestion 5 of 15 Loading... 6. What is a catalyst?A substance that slows down a chemical reaction but is chemically unchanged at the end of the reactionA substance that speeds up a chemical reaction but is chemically unchanged at the end of the reactionA substance that helps dissolve insoluble reagents to speed up the rate of reactionA substance that speeds up a chemical reaction but is used up as the reaction proceedsQuestion 6 of 15 Loading... 7. 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) decrease rate of reaction1) more particles exposed 2) less frequent collisions 3) decrease rate of reaction1) more particles exposed 2) more frequent collisions 3) increase rate of reaction1) more particles exposed 2) less frequent collisions 3) increase rate of reactionQuestion 7 of 15 Loading... 8. Explain how a catalyst worksA catalyst reduces the activation energy of the reactionA catalyst provides an alternative pathway with lower activation energyA 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 reactionQuestion 8 of 15 Loading... 9. 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 less steeply. Levels out at lower level.Line rises at same rate, but levels out at a higher level.Line rises more steeply. Levels out at higher level.Line rises more steeply. Levels out at same level.Question 9 of 15 Loading... 10. Give a simple reaction can be used to investigate the effect of changing surface area on the rate of reactionHydrochloric acid added to either marble chips or powdered calcium carbonateLarge chips or powdered ion ore reacted to produce iron using the displacement methodBurning powdered magnesium or strips of magnesium in airLarge chips or powdered sodium nitrate added to hydrochloric acidQuestion 10 of 15 Loading... 11. Give a simple reaction can be used to investigate the effect of changing concentration on the rate of reactionIron ore of various concentrations reacted via the displacement method to produce ironEthene of various concentrations reacted with water to make ethanolSodium hydroxide of various concentrations added to hydrochloride acid to produce sodium chlorideMarble chips added to hydrochloric acid of various concentrationsQuestion 11 of 15 Loading... 12.

What type of substance speeds up a chemical reaction but is chemically unchanged at the end of the reaction?SoluteCatalystReagentOreQuestion 13 of 15 Loading... 14. 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 twice the volume of the acid?Line rises more steeply. Levels out at same level.Line rises more steeply. Levels out at a level twice as high as the original.No change. Line would look the same.Line rises at the same rate, but levels out at twice the height.Question 14 of 15 Loading... 15.
