Determine if the following statements are correct regarding the graph of rate data above? The half-life, t1/2, is independent of the initial concentration The rate constant, k, would have units of M-1 s-1  Doubling the concentration of A would not change the rate of the reaction.

Below is a representation of an acid in water.  Which of the following statements is/are correct about the following image: The percent ionization of the acid would be 100% The acid could be chloric acid The acid could be acetic acid

Determine which of the following statements are True or False about 500.0 mL of buffer consisting of 2.1 M pyruvic acid (HC3H3O3) and 3.6 M sodium pyruvate (NaC3H3O3): The pH slightly decreases when 25.0 mL of 0.50 M hydrochloric acid is added to the buffer but the buffer is still effective 0.250 moles of sodium hydroxide will be neutralized by pyruvic acid and the buffer is still effective 0.125 moles of hydrochloric acid will be neutralized by pyruvic acid and the buffer is still effective
