If the reaction of zinc with 6M HCl at room temperature 20oC described in question #5 above took 30 seconds at 20 oC, predict the time the reaction would take at 10 oC.
Homework Answers
on an average on decreasing temperature by 10 degree celcius, reaction rate decrease to half of initial so time taken will double. here it takes 30 seconds at 20 degree celcius so it will take 60 seconds at 10 degree celcius
60 seconds is answer.
