chemical reactions - Coggle Diagram
chemical reactions
chemical world
students should be able to investigate effect of variables on chemical reactions
should be able to consider chemical reactions, interms of energy +understand energy profile diagrams
thermics
exothermic
gives out heat a reaction which produces heat
endothermic
absorbs heat from surrounding area
definition
when a new product is formed
example rusting (iron oxide= Fe+O2=iron oxide)
biochemical
a reaction that occurs inside of a cell
biochem happen in the mitochondria (power house of the cell)because respiration happens here)
formula for respiration: C6H12O6,+6O2--> 6Co2+6H2o)
rate of reaction
how fast or slow it takes the reactants to turn into a products.
what may affect r.o.r
Temoerature: increases temp giving particles more energy+colliding more with each other-> cooling temp opposite effect
concentration of reactants
surface area
catalyst
speeds up the rate of a reaction without being used up in the reaction
enzymes are a catalyst in the body( digestive system reactions)
energy profile diagrams
display visually the change in energy during a reaction
