Acetic acid and water react to form hydronium cation and acetate anion, like this: HCH3CO2(aq)+H2O(l)H3O(aq)+CH3CO2(aq ) .
Imagine 250. mmol of HCH3CO2 are removed from a flask containing a mixture of HCH3CO2, H2O, H3O and CH3CO2 at equilibrium, and then answer the following questions.
What is the rate of the forward, before any CH3CO2 added in water?
A. Zero
B. Greater than zero, but less than the rate of the reverse reaction.
C. Greater than zero, and equal to the rate of the reverse reaction.
D. Greater than zero, and greater than the rate of the reverse reaction.

What is the equilibrium constant of aa+bb=cc+dd

14. many depressants reduce small muscle control, making it harder for a. you to steer b. your mind to consider complex problems c. the eye to scan, focus, or stay still d. the kidneys to filter alcohol out of the bloodstream

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.
