Rates of Reaction facts Flashcards
what does the rate of reaction tell us
it tells us the speed of which a reaction occurs
what are 4 factors that can change the rate of reaction
Increasing tempereture , increasing cosentration , decreasig particle size & adding a catalyst / enzyme
what will increasing temp do
speed up rate of reaction
what will decreasing temp do
slow down rate of reaction
what will increasing particle size do
slow down rate of reaction
what will decreasing particle size do
speed up rate of reaction
what will increasing concentration do
speed up rate of reaction
what will decreasing concentration do
slow down rate of reaction
what will adding a catalyst / enzyme do
speed up rate of reaction
what is a catalyst
A substance that increases the rate of a chemical reaction without being used up.
what is an enzyme
a biological catalyst & are found in all living cells
what temp does an enzyme work best at
human body temp - 37C
name 2 types of enzymes
Carbohydrase , Zymase , Invertase , Protease
what is a chemical reaction
One or more substances that form to make a new product
factors of chemical reaction
colour change , Energy given out ( Light ,heat , sound) , Solid appears/disappears , Gas is produced
