K= [X] [OH-]

conc of X = 0.024

conc of OH- = 0.035

K= 0.101

• in a second experiment at the same temperature, water was added to the original reaction mixture so that the total volume was doubled. Calculate the initial rate of reaction in the second experiment. (2 marks)
• the sample produced consists of a racemic mixture. Explain how this mixture is formed. (2 marks)
• the reaction is zero order with respect to B. State the significance of this zero order for the mechanism of the reaction (1 mark)

rate = K[E]

• explain why doubling temperature has a much greater effect on the rate of reaction than doubling the concentration of E (3 marks)
• suggest why the order of reaction with respect to NaOH appears to be 0 under new conditions (there is a higher conc of NaOH now)
