Question
Consider the reactiorn If an equilibrium mixture of these three substances is compressed, equilibriumw 20. a shift to the left21. a higher pressure favors fewer mols b. shift to the left c shift to the right d. shift to the right e, be unchanged c.solid NH.Cl does not appear in the equiibrium expression 22. An endothermic reaction that results in more moles of product than reactant gas will be product-favored under conditions of a high b. high c. high d. low e. low high low high For 23-28, consider the equilibrium system: c() + coag)-2000 ??" +106M/mel 23. If more Co) is added, the equilibrium will 24. If CO is removed the equilibrium will 25. If the pressure is increased on the reaction mixture the equilibrium wil 26. If the volume is increased on the reaction mixture the equilibrium wil 27. If the temperature is increased on the reaction mixture the equilibrium will 28. If a catalyst is added, the equilibrium will a. shift to the left (to make more reactant) b. shift to the right (to makce more product) c. be unchanged 29. Consider this reaction at equilibrium: If the reaction is cooled, the equilibrium willbecause shift to the left; a. b. decreased temperature favors an endothermic reaction decreased temperature favors an exothermic reaction shift to the left: c shift to the right; d. shift to the right; e. be unchanged; decreased temperature favors an endothermic reaction decreased temperature favors an exothermic reaction temperature has no effect on equilibrium g ra If the pressure is increased (by compressing the mixture), equilibrium will shift to the if the pressure is increased by adding an inert gas, the equilibrium will a. left; b. right; c. right; d. left e. right; shift to the left shift to the left remain unchanged remain unchanged shift to the rightExplanation / Answer
20 & 21. Shift to the left ; higher pressure favours fewer moles of gas.
22. High pressure & low temperature.
23. Shift to right
24. Shift to left
25. Shift to fewer gas molecules.
26. shift to more gas molecules.
27. towards endothermic reaction.
28. Be unchanged
29. Shift to the right ; decreased temperature favours an exothermic reaction
30. Left ; remain unchanged
