The following pictures represent mixtures that
contain A atoms (red), B atoms (blue), and AB
and B, molecules, what interconvert accorchng
to the equation A w B, CAB + B. If mixture (1) is
at equilibrium, which of the other mixtures are
also at equilibrium? Explain.
The given reaction is A+B2 AB+B. Write the
equilibrium constant for the reaction as follows:
PkBilB K1 EARBi]
The units of concentration are mol / L At
constant volume, the reaction is change with
the number of moles participate in the reaction
only. So, the equilibrium constant is
Kc _ moles Of B7 Of AB fA moles f B,
From the given data, the mixture (1) is at
equilibrium. So, calculate the equilibrium
constant for all mixtures and compare the
