Le Châtelier’s principle is related ultimately to the rates ofthe forward and reverse steps in a reaction. Explain (a) why anincrease in reactant concentration shifts the equilibrium positionto the right but does not change K; (b) why a decrease in Vshiftsthe equilibrium position toward fewer moles of gas but does notchange K; (c) why a rise in Tshifts the equilibrium position of anexothermic reaction toward reactants and also changes K;and(d) why a rise in temperature of an endothermic reaction from T1to T₂ results in K₂ being larger than K1

I Review Constants Periodic Table For a certain chemical reaction, AH° = -35.8 kJ and AS° = -80.0 J/K. Part A Is the reaction exothermic or endothermic? O exothermic O endothermic Submit Prevlous Anewere v Correct Anegative enthalpy value indicates that energy is released by the system. Therefore, the reaction is exothemic. Part B Does the reaction lead to an increase or decrease in the disorder of the system? O increase O decrease Submit Previous Anawere v Correct The sign of the entropy change is negative, which indicates that the disorder, or entropy, of the system has decreased. • Part C Calculate AG for the reaction at 208 K.
