9.9—Many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of

Know that many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of the forward reaction is equal to the rate of the backward reaction ii the concentrations of the reactants and the products remain constant.

Use —many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of to connect the rule to the data and decision in the question.

This matters because —many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Many reactions are readily reversible and that they can reach a state of dynamic equilibrium in which: i the rate of is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
