Kinetics Free Response Sample Questions
Kinetics Free Response Sample Questions Name: AP Chemistry Period: Date: RF Mandes, PhD, NBCT. Answer the following Questions on a separate sheet of paper 1971. Ethyl iodide reacts with a solution of sodium hydroxide to give ethyl alcohol according to the equation. CH3CH2I + OH- CH3CH2OH + I- The reaction is first order with respect to both ethyl iodide and hydroxide ion, and the overall-rate expression for the reaction is as follows: rate = k[CH3CH2I][OH-]. What would you do in the laboratory to obtain data to confirm the order in the rate expression for either of the reactants? Answer: The molar concentration of the hydroxide ion [OH -] can be determined by conducting the above reaction with a pH meter monitoring it.
