4) To determine the equilibrium just combine the initial and the change. J. Now we can write the equilibrium expression and plug in our equilibrium values from the table and solve for x algebraically. K=[H2][CO2][H2O][CO]=[1Mx][1Mx][x][x] Further examples Write a table and equilibrium expression with equilibrium concentrations for the following equilibrium equations. Initial HO2(g)+NO2(g)HO2NO2(g)[HO2]=[NO2]=1M[HO2NO2]=0 Answer K=[HO2][NO2][HO2NO2]=[1Mx][1Mx][x] 4) To determine the equilibrium just combine the initial and the change. J.
