Inquiry question: What happens when chemical reactions do not go through to completion?
Students:
● conduct practical investigations to analyse the reversibility of chemical reactions, for example:
– cobalt(II) chloride hydrated and dehydrated
– iron(III) nitrate and potassium thiocyanate
– burning magnesium
– burning steel wool (ACSCH090)
● model static and dynamic equilibrium and analyse the differences between open and closed systems (ACSCH079, ACSCH091)
● analyse examples of non-equilibrium systems in terms of the effect of entropy and enthalpy, for example:
– combustion reactions
– photosynthesis
● investigate the relationship between collision theory and reaction rate in order to analyse chemical equilibrium reactions (ACSCH070, ACSCH094)
