Effect of Change in Concentration (at Constant Tem perature) Add reactant or product +system shifts away from added component Remove reactant or product = system shifts towards removed component 1) Initially, Q changes But: K is unchanged (at constant T) 2) Concentrations change -+ back to equilibrium : Q -+ K Example: Haber process Nr(s)+3Hr(s) +2NH3k) To increase yield of products: l)Increase tNzl or [Hz] 2) Remove product (NIH3) Continuous product removal -+ completion 5 Effect of Ghange in Pressure (at Gonstant Temperature) NrG) [email protected]) - 2Mr(g) 3 Ways to Change Pressure: 1) Add or Remove a gaseous reactant or product at constant volume -+ Same result as change in concentration Z)Jlleninefear(one that is not involved in the reaction) at constant vnh.me -+ increase total pressure BUT Does NOT change partial pressures
