Objective: To identify the conditions that exist at equilibrium,
to comprehend the meaning of he equilibrium concept (K), and to use the

Tap the statements to identify them as being True (T) or False (F).
Consider the three statements. Identify the 2 True and the 1 False
statement.
Consider the reversible reaction:
The particle diagrams below represent the mixture of reactants and
products present at equilibrium for three different temperatures.
Relate each diagram to a relative K value, with the options being:

Consider a reversible system:
R(g) ⇄ G(g)
The Concentration-Time graphs for three such systems is shown. One of
these systems is not like the others. For instance, two have a large K
(the equilibrium position lies far to the right) while the other has a
small K ... or vice versa. In terms of their K value, which one doesn't
belong?
Tap a statement to select or deselect it. Select all that apply.
Consider a reversible system: A(g) ⇄ B(g)
The value of K = 4.5.
The initial conditions show that [B] / [A] = 2.1. Which of the
following would be expected to occur in order for the system to reach
an equilibrium state?
Consider the reversible system represented by the generic
equation:
A(g) ⇄
B(g)
