Question

paper) Post lab Questions 1. Explain what is meant by an equilibrium constant. Was the value constant for all your experiments? Should it be constant? Why or why not? 2. What does the calculated experimental value of the equilibrium constant, Ko indicate regarding the degree of completeness of the reaction? In other words, at equilibrium, were there mostly products, reactants, or relatively large amounts of both? Explain. 3. When you use a spectrophotometer, should you set the wavelength of light to be the same color as that of the solution, or would a different color be more appropriate? Explain. 4. What was the color of visible light chosen for this experiment? What was the color of the MGH ion? 48
These questions are refering to the reaction MG + H+ <------> MGH+. throughout the experiment, my calculated equilibrium constants were all different.

Thanks so much!

Answer 1

OEquilibrium constant ! reactio When ' the or ton wand rate The rate agets equalled to the rate or backward reaction, the state or. the reaction is known as equilibrium and the value ofroit's reaction quotient is known as Equilibrium Constenlo s), od for a reactional a A tb B ce it a b Ka [CÍ CDIO Hellows coses [Aja [Bob - Yes the the equilibrium valhe constant should be same for the reaction lla mg thi - Mig Hp A, throughout the experiment as equilibrium constant is not arrected by the catalyst on addition or catalyst - But if you are changing the temperature through out the reaction, the equilibrum constant will change According to updated HomeworkLib policy I only answered . the hirst question asked by you
