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.
