Indicate the CORRECT statement regarding concentrations at equilibrium:

A new experiment, for which the balanced chemical equation is unknown, was performed in the lab.

$aA(aq)+bB(aq)\rightleftarrows dD(aq)$

The concentrations of the different species (A, B and D) were monitored and plotted as a function of time, as shown below. Which of the following statements concerning this reaction is true?

Choose which statement completes the following sentence to make it false. Once a dynamic equilibrium is reached ----------------

Choose which statement completes the following sentence to make it false. Once a dynamic equilibrium is reached ----------------

Indicate the CORRECT statement regarding concentrations at equilibrium:

The graph below shows the rate of the forward (top curve) and reverse (bottom curve) over time

Which of the following statements are CORRECT

i. After point B the forward and reverse rates are equal because [products]=[reactants]

Consider this balanced chemical reaction and the molecular representation for both of the next two questions: $2AB(g)⇌A_2(g)+B_2(g)$

Choose which statement completes the following sentence to make it false.

Once a dynamic equilibrium is reached ___________

The digestion of some high-protein foods such as red meat, beans, lentils, and shell-fish, releases uric acid, HC5H3N4O3(aq), which ionizes into hydrogen ions, H+(aq) and urate ions, C5H3N4O3-(aq) in the bloodstream. People whose kidneys do not function properly cannot excrete urate ion sufficiently quickly, leading to an increased concentration of urate in the blood. This sometimes leads to a painful form of arthritis known as gout, characterized by the formation of tiny needle-like crystals of sodium urate, NaC5H3N4O3(aq), in joints and tissues according to the equation:

NaC5H3N4O3(s) ⇌ Na+(aq) + C5H3N4O3-(aq)

a) Suppose you are a nutritionist. What advice could you give to your patients who suffer from gout? Explain why the advice would be effective [2]
