Question

relation on the set is defined by the condition: if and only if belong to the blue rectangle (see the picture below): which of the sets below correspond to this relation? (recall: we used dashed lines to exclude points on the boundary of a set, and solid lines to include them.)

Answer 1

The answer involves applying chemical kinetics principles to determine if equilibrium is reached in a given reaction by examining the concentrations of reactants and products over time.

Step-by-step explanation:

The student’s question relates to a mathematical concept where variables are represented by different shapes in a chemical concentration scenario to explore the concept of equilibrium.

They are asked to determine which of the given systems has reached equilibrium based on the given mixtures composition changes over time.

To solve problems involving reactions and equilibrium, one typically applies the principles of chemical kinetics and the law of mass action. Equilibrium is achieved in a reaction when the rate of the forward reaction equals the rate of the reverse reaction, and the concentrations of reactants and products remain constant over time.

Graphical or tabular data representing concentrations over time can be used to identify when equilibrium is reached. If the information shows constant concentrations of all reactive species at different time intervals, the system is at equilibrium.

To identify equilibrium in the provided illustration, the composition of mixtures at different times t₀, t₁, and t₃ would need to be examined. If the quantities of A, B, and C remain constant from one time point to the next, then the system could be considered at equilibrium.
