Flashcards
Chemistry - Rate Of Reaction.
Cards in this deck (6)
- 1What does Rate Of Reaction depend on?1) Temperature
2) Concentration (Or pressure in gases)
3) Catalyst
4) Surface Area Of Solids (Or size of solid pieces.) - 2What are the 3 different ways to measure the Rate Of Reaction?1) Precipitation
2) Change in mass (Usually gas has been given off)
3) The Volume of gas given off. - 3What increases the amount of collisions?1) Higher Temperature
2) Higher Concentration
3) Larger Surface Area - 4Define CatalystA catalyst is a substance which speeds up a reaction, without being changed or used up in the reaction.
- 5What is an Exothermic reaction?A reaction which transfers energy to the surroundings, usually in the form of heat and usually shown by a rise in temperature.
- 6What is an Endothermic Reaction?An Endothermic Reaction takes energy in from the surroundings, usually in the form of heat and can be shown by a drop in temperature.
