Calcium carbonate reacts with an excess of hydrochloric acid in a flask. The mass of flask and contents decreases over time as the carbon dioxide escapes. This is shown on the graph. How would the graph look different if the reaction was done at a higher temperature?Line falls at the same rate. Levels out at a higher level.Line falls at the same rate. Levels out at a lower level (but still above zero).Line falls more steeply. Levels out as same level.Line falls more steeply. Levels out at a lower level.Question 6 of 15 Loading... 7. What happens if two particles collide with less than the activation energyThe particles fuse togetherThe reaction only goes partwayNo reactionThe reaction still occurs but very slowlyQuestion 7 of 15 Loading... 8. Write the chemical equation for the decompostion of hydrogen peroxide, H₂O₂H₂O₂ → 2H₂O + O₂H₂O₂ → H₂O + O₂2H₂O₂ → 2H₂O + O₂4H₂O₂ → 2H₂O + O₂Question 8 of 15 Loading... 9.

What is a catalyst?A 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 proceedsA 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 reactionQuestion 11 of 15 Loading... 12. 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 12 of 15 Loading... 13.
