At a particular temperature, k 5.0 x 10-6 for the reaction 2co2(9) 2co(9) +02(9) if 3.0 moles of co2 is initially placed into a 5.0-l vessel, calculate the equilibrium concentrations of all species. co2] co] o2l [02]-

Answer : The concentration of at equilibrium will be, 0.598 M, 0.00216 M and 0.00108 M respectively.

Explanation : Given,

Equilibrium constant =

tex]\text{Concentration of }CO_2=\frac{\text{Moles of }CO_2}{\text{Volume of solution}}=\frac{3.0mole}{5.0L}=0.6mole=0.6M[/tex]

The balanced equilibrium reaction is,

Initial conc.     0.6 M                 0             0

At eqm.        (0.6-2x) M          2x M         x M

The expression of equilibrium constant for the reaction will be:

Now put all the values in this expression, we get :

By solving the term 'x', we get:

Concentration of at equilibrium =

Concentration of at equilibrium =

Concentration of at equilibrium =

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
