Question

At 900 °C, K = 0.0108 for the reaction CaCO3(8) F CaO(s) + CO2(g) A mixture of CaCO3, CaO, and CO2 is placed in a 10.0-L vessel at 900 °C. For the following mixtures, will the amount of CaCO3 increase, decrease, or remain the same as the system approaches equilibrium?

Answer 1

Past Air Caloes) Caoco + CO2 con Ke= [202]. = 0.0108 M. 4251 Concentration of CO2 = t to = 0.00966 m. Qc = [CO2] = 0.00966 M. As Ocake. The equilibricam strift towards Right So that concentratia, of cacos Decreases. Anslufy decreases 5-66 1 Pant Bi Cancentration of CO₂ = to 44 10 - 0.0129 M De = [CO2] = 0.0129M. As Qe > Ke. The equilibrium shift towards left. So that, Concentration of caco Increases. Answe', Increases, past c- carrentration of CO2 = Sexto = 0.015 M. 1. Qe = [Co2] = 0.015m. As Qe> Kc. equilibrium shift towards left. so that, Concentration of caces increasel. Ansut Increase

Answer 2

correct options are

decrease

increase

decrease
