The times taken for iodine to be liberated in the reaction between sodium thiosulphate and hydrochloric acid at various temperature are as follows. These results suggest that
for a 10o rise in temperature, rate of reaction is double
for a 10 o rise in temperature, rate of reaction is halved
time taken for iodine to appear does not depend on temperature
for a 10 o rise in temperature rate of reaction is tripled
Correct answer is B
The iodine liberation process is significantly affected by the amount of acid, that of potassium iodide added, the waiting time for the liberation, and light; therefore, the process plays a key role for the accuracy of the titration results.
for a 10 o rise in temperature, rate of reaction is halved
