Document Summary

Chapter 15: system at equilibrium: two opposing processes take place at equal rates; affects vapour pressure of a liquid, solubility of a solute, distribution coefficient represent physical equilibrium; decomposition of. If q < k, a net change occurs form left to right (forward reaction) When the volume of an equilibrium mixture of gases is reduced, a net change occurs in the direction that produces fewer moles of gas. When the volume is increases, a net change occurs in the direction that produces more moles of gas: temperature: raising the temperature of an equilibrium mixture shifts the equilibrium condition in the direction of the endothermic reaction. Lowering the temperature causes a shift in the direction of the exothermic reaction: catalyst: speeds up forward and reverse reactions, equilibrium is achiever faster, but amounts are unchanged (doesn"t cha(cid:374)ge (cid:374)u(cid:373)erical value of co(cid:374)sta(cid:374)t) 461 h kj/mol: requires high pressure (250 atm), moderate temperature (400 degrees) fe catalyst.
