The reaction rate constants for an investigation of ascorbic acid deterioration in a multivitamin mix during storage at different temperatures were:

Temperature (^oC)	20	30	50	60	70
Reaction constant (mgml^-1day^-1)	0.00062	0.024	0.24	0.66	0.18

(i) Determine the activation energy at 70 oC

(ii) Determine the rate constant at 80 oC

(iii) Suppose the temperature increased from 20 oC to 70 oC, determine the sensitivity of the reaction rate to this rise is temperature.

(iv) At what time would the ascorbic acid deteriorate by 50%?

Expert Solution

Here,for calculating the exact time for 50% detoriation ,initial concentration and the temperature at which the reaction is taking place should be given. I have assumed the reaction at T = 50°C at found the half life time.

In this experiment the concentration of Vitamin C/ascorbic acid is used to find the amount of iodine present through titration and the stoichiometric ratio. Furthermore, by finding the amount of iodine present before and after the equivalence point, the experiment presents us with the amount of iodine that reacts with the Vitamin C in “unknown B”.There were two titrations performed in this experiment, three times each. The first began with 50mL of Sodium Thiosulphate put in a burette. Approximately 2g...
