dynamic equilibrium
is where the foward reaction is happening at the same rate as the backward reaction
1 of 11
le chatelier principle
equilibruim will shift to minimize the chages
2 of 11
what happens when increase temp
increase temp for an exothermic reaction the enthaoly chnage will shift to the right, increase temp for a endo thermoic reaction the nethaply change will shift towards the left
3 of 11
what happens when you increase pressure
the enthaply chmage will shift to the side with the least amount of moles
4 of 11
what happenes when you increase concentration
if you incease the concentration of the products the equilibrium will shift toward the reactions and produce more reactants,if the concentration of the reactants is increased then the equilibruim will shift towards the products and produce more
5 of 11
what is the acid ionisation eqaution fior equilibrium
H+ + OH- = H2O
6 of 11
what does and acid make when reactwith base
acid + base = salt + water HCL+ NaOH = NaCl + H20 also the same with sulphuric acid
7 of 11
what are acids
acids are proton donours
8 of 11
what os the diffrence between hydrochloric acid and ethanoic acid
, hydrochloric acid completely ionises in water and is a strong acid, ethanoic acid partially ionises in water and is a weak acid
9 of 11
what is a base
is a proton exepter
10 of 11
describe the pH scale
the pH scale ranges from 1-14 1 being the most acidic and 14 being the most alkaline, a ph 7 is a neutral solution
