Question

if it takes 20 h to convert 100g of reactant A to roduct C at 20 degrees celcius, approximately how many minutes would it take at 110 degrees celcius? I know the answer, I just don't know how to get the answer

Answer 1

I THINK what this problem is driving at is that the rate of a reaction approximately doubles for every 10 degree rise in T. So count the number of 10 "degrees" from 20 to 110 (call that number n), then (1/2^n) x 20 hr = ??hours, then convert to minutes. I obtained a little more than 2 minutes.
