CHM110H5 Lecture Notes - Lecture 12: Reaction Quotient, Inert Gas, Sulfur Trioxide
Document Summary
Increase p by adding more reactants or products at constant v. Increase the p by adding an inert gas at constant v. Add an inert gas and let v increase so as to maintain the a. a. b. c. d. i. ii. iii. iv. How can the yield of so3 be decreased: p decrease, v increase, shift left, t increase, v increase, shift left, k decrease, remove so2 or o2, add an inert gas, v increase. *note: changes the numerical value of k: uses, direction of spontaneous reaction (q = reaction quotient, equilibrium cconcentrations, extent of reaction. For h2 + i2 2 hi , k=55. 3 at 700k. Q = (0. 7)^2/(0. 02)^2 = 1225 > 55. 3 = 55. 3 k. Q > k therefore, reaction to the left. H2 = 0. 0783 i2 = 0. 0783 hi = 0. 5833. For co2 + h2 co + h2o k=0. 10 at 690k.
