Part iii. acetic acid is a weak acid and establishes the following equilibrium in water: hc2h3o2(aq) + h2o(l) h3o+(aq) + c2h3o2-(aq). in part iii, the methyl orange indicator is used to monitor the equilibrium shifts of the acetic acid/acetate ion system. the methyl orange equilibrium established with water is hmo(aq)(orange-red) + h2o(l) h3o+(aq) + mo-(aq)(yellow). you compared the color of the solutions in three test tubes that initially contained 3 ml of 0.1 m acetic acid and a few drops of methyl orange indicator. in the first test tube, you added 1.0 m nac2h3o2 drop wise. what color change was observed and what did this color change indicate about the shift in the methyl orange equilibrium? a. the solution turned a more intense orange-red color indicating that the methyl orange equilibrium shifted to the left, producing more of the orange-red colored hmo. b. the solution turned yellow indicating that the methyl orange equilibrium shifted to the right, producing more of the yellow colored mo-. c. the solution turned yellow indicating that the methyl orange equilibrium shifted to the left, producing more of the yellow colored mo-. d. the solution turned a more intense orange-red color indicating that the methyl orange equilibrium shifted to the right, producing more of the orange-red colored hmo. e. no color change was observed indicating that equilibrium was unaffected.

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
