Question

3. The reaction 2 S026) + O2(e) -------> 2 SO3(g) + heat is an exothermic reaction How will each of the following changes affect the equilibrium concentrations of each gas once equilibrium is re-established, i.e., will the reaction shift right or left? a. adding more O2 to the container b. adding more SO3 to the container c. condensing and removing SO3 d. placing the container in a hot plate e. cooling the container

Answer 1

03 Given Seaction is (a) 180,(g) + O2(g) = 250, (g) + Heat (Exothennu's herchon Ans. Adding More Og to the container Equilibrium will shift towarels sight (forward direction). As, According to le chatelier principle, if we increase the concentration of reactant, the equilibrium will shift in the direction in which there is decrease in concentration of reactants means to the Product side. (b). Adding more So, to the container → Equilibrium shift towards left (in backward direction). As According to le chatelier principle, if we increase procluct concentration, equilibrium shift in the direction in which there is decrease in concentration of Product means to the reactant side. (backward direction) (c) Condensing and removing Sozi equilibrium shift in the direction in which more soz is formed. so equilibrium shift in the ele forward direction (d) Placing the container in a hot plate- will increase the temperature of the container so equilibrium will shift in the direction in which there is decrease of temperature, so equilibrium will shift in the backward

direction as it is endothermic reaction. le) Cooling the container - amemeans m decrease the temperature of container, so equilibrium shift in the direction in which there is increase of temperature. so equilibrium shift in the forward direction as it is exothermic reaction.
