Composit ion: 0.613 mo l ¾¾ ® 3 H2 (g) ¬¾ ¾ CH4 (g) 1.839 mo l + 0.387 mo l + H2O (g) 0.387 mo l What changes in the amount of reagents would produce more CH4? Ø increase amount of CO or H2 Ø remove CH4 or H2O Ø Most practical and least expensive so lut ion is to remo ve H2O (cool reaction mixture to condense water vapor) CO (g) Molar Equil. Composit ion: + 0.613 mo l ¾¾ ® 3 H2 (g) ¬¾ ¾ CH4 (g) 1.839 mo l 0.387 mo l H2O (g) 0.387 mo l - 0.387 mol Stress: Response: + Equilibrium shifts New Equilibrium Co mposit ion: 0.491 mo l decreased 1.473 mo l decreased 0.509 mo l increased 0.122 mo l decreased · Equilibrium shift can also be predicted fro m an evaluat ion of Qc (React ion Quotient) 24 Chemistry 102 Chapter 14 EFFECT OF PRESSURE CHANGE ON EQUILIBRIUM · A change in pressure has an effect on equilibrium only when the fo llowing two condit ions exist: 1. At least one of the reacting species (reactant or product) is a gas. 2. Total number of mo les of gaseous reactants ¹ Total number of mo les of gaseous products · The Pressure of...
