In the study of oxidation of iodide ions by hydrogen peroxide in presence of dilute `H_(2)SO_(4)`, thiosulphate and starch as a clock reaction, if concentration of iodide ions is increased

A

less time will be taken for blue color to appear

B

more time will be taken for blue colour to appear

C

same time will be taken for blue colour to appear

D

any one of the above can happen depending upon the amount of `H_(2)SO_(4)` present.

Text Solution

Verified by Experts

The correct Answer is:
A
On increasing the concentration of `I^(-)` ions, the rate of reaction will increase. After reaction with thiosulphate, less time will be taken for blue colour to appear.

The stoichiometric equation for the oxidation of bromide ions by hydrogen peroxide in acid solution is 2Br^(-) + H_2O_2 + 2H^(+) to Br_2+ 2H_2O Since the reaction does not occur in one stage, the rate equation does not correspond to this stoichiometric equation but is rate = k[H_2O_2][H^+][Br^-] If the concentration of H_2O_2 is increased by a factor of 3, by what factor is the rate of consumption of Br^– ions increased ?
