Flashcards in Chemical Reactions Deck (6)
4 Signs that a chemical reaction has happened?
Effervescence ( gas released), colour change, temperature change, precipitation (solid formed)
What is an Exothermic reaction
A reaction which releases energy ergo warm/hot to touch
What is an Endothermic reaction?
A reaction which absorbs heat ergo feels colder
What can make the rate of reaction quicker?
Higher concentration, Smaller particle size, Increase in temperature, Catalyst
What can slow down the rate of reaction?
Lower Concentration, Big particle size, Decrease in temperature
