Calculating Equilibrium Concentrations.
Consider the reaction SO2(g) + NO2(g) = NO(g) + SO3(g) at 460 C. What are the equilibrium concentrations of all reactants and products if the initial concentrations are [SO2]o = [NO2]o = 3.00 x 10-3 M and [NO]o = [SO3]o = 4.00 x 10-2 M? The value of the equilibrium constant for the reaction is 85.0 at 460 C.
Set up table with initial, change, and equilibrium expressions:
SO2(g) + NO2(g) = NO(g) + SO3(g)
I 3x10-3 3x10-3 4x10-2 ...
This solution uses a table format to calculate the all the equilibrium concentrations.
