Given the reaction at equilibrium: C(s) + O2(g) → CO2(g) + heat Which stress on the system will increase the concentration of CO2(g)? increasing the temperature increasing the concentration of 02(g) decreasing the pressure on the reaction decreasing the amount of C(s)
Answers
Answer:
Increase in temperature and decrease in volume:
As increase in temp. shifts backward but decrease in volume shifts forward.
Addition of CO and increase in temperature at constant volume:
As addition of CO shifts reaction forward but increase in temp. shifts it backward.
According to-
LE-CHATELIER'S PRINCIPLE : According to this principle. If a system at equilibrium is subjected to a change of concentration, pressure or temperature, the equilibrium is shifted in such a way as to nullify the effect of change.
(a)Change in concentration : In an equilibrium increasing the concentrations of reactants results in shifting the equilibrium in favour of products while increasing concentrations of the products results in shifting the equilibrium in favour of the reactants.
