(c) Reversible reactions and equilibria (Content in blue is not required for Double Award Science) |
3.17 know that some reactions are reversible and this is indicated by the symbol in equations |
3.18 describe reversible reactions such as the dehydration of hydrated copper(II) sulfate and the effect of heat on ammonium chloride |
3.19C know that a reversible reaction can reach dynamic equilibrium in a sealed container |
3.20C know that the characteristics of a reaction at dynamic equilibrium are:
- the forward and reverse reactions occur at the same rate
- the concentrations of reactants and products remain constant
|
3.21C understand why a catalyst does not affect the position of equilibrium in a reversible reaction |
3.22C know the effect of changing either temperature or pressure on the position of equilibrium in a reversible reaction |
