Question 19 (2 points) Identify each of the following as a homogeneous or heterogeneous eq uilibrium 4HCI@+020 2H20 7+2Cl29 CH«+H20 3H2g+CO 1. homogeneous equilibrium 2. heterogeneous equilibrium 2NaHCO3) = Na2C030+C020+H20 2030 3029 Question 20(1.5 points) Co+ H2+ 31 kcal - H269 + Coa Indicate how each of the following will affect the equilibrium concentration of CO in the following reaction: 1. This will cause an increase in the equilibrium concentration of CO decrease the temperature of the reaction add a catalyst 2. This will cause a decrease in the equilibrium concentration of CO remove some H20 3 No change will be observed in the equilibrium concentration of CO

Answer 1

Solution :- #19: Of all reactants and Products are in same phase is same Physical state, equilibrins is said to be homogenirs otherwise heterogeneors. 2H20 et → Hetrogeneos i) 4 hl g + Ozcan 2u2go ii) My got 120 g) ,+ 1120 g) 2 312 g) + CO co go Homogenes in) a Nall coz $2 Na2103 iv) g039) 302go stolgth 20 g) Herrogeniors Homogenoy

#20 of Co- Csg + H2D gg +31 KG1 Hz. g) + (Og is decrease the temperature af reactis 2. This will Guse a decrease in the equilibrem concentrats Explanatos: Since reactions is endothermic ef- for word reaction is favored with increase intemperatis ii) add a Catalyst 3. No change will be observed in the equilibriums Concentrations ga Explanations : - Presence of Catalyst does not affect bolition of equilibrum. It accelerate the rate af forward and backward reaction to the same extent' co.

af co rü removing some H2@g) →2. This will cause a decreme in the equilibruns concentratis Explanats:- According to Le Chatellier's Prinuple, removal of reactant shifts equilibrum in backward directions the
