chp 11 - endo + exo

Cards (5)

forward reaction
if equilibrium shifts so the forward reaction is favoured (reactants - products) we say equilibrium shifts to the right (more products are made)
backwards reaction 
if equilibrium shifts so the backwards reaction is favoured (products - reactants) we say equilibrium shifts to the left (more reactants are made)
exothermic
more reactants, less products
activation energy = difference between top and reactants level
energy released = difference between reactants and products
change is negative
endothermic
less reactants, more products
activation energy = difference between top and reactants level
energy absorbed = different between reactants and products
change is positive

when you add the catalyst you need less energy required for the reaction to happen than if you don't have it
when you use a catalyst it also speeds up the reaction as the particles themselves don't need as high of activation energy
