Answer : The equilibrium concentration of is, 0.50 M
Explanation : Given,
Initial moles of = 0.65 mole
Volume of solution = 1.0 L
Moles of at equilibrium = 0.15 mole
The balanced equilibrium reaction will be,
Initial moles 0.65 0 0
At eqm. (0.65-x) x x
Moles of at equilibrium = x = 0.15 mole
Moles of at equilibrium = x = 0.15 mole
Moles of at equilibrium = (0.65-x) = (0.65-0.15) = 0.50 mole
Now we have to calculate the concentration of at equilibrium.
Formula used :
Therefore, the equilibrium concentration of is, 0.50 M
