Question

At 26°C, fresh cow’s milk will sour in 6.0 hours but it will take 50.0 hours to sour in a refrigerator set at 6°C. How long will it take for the same amount of milk to sour if the temperature it is refrigerated at is a temperature of 17°C Remember units of k = sec^-1

Answer 1

We know that for every raise in ten degree celcius the rate of reaction should double

That is milk at 6^o C is raised to 16^o C the rate of reaction is doubled and therefore reaction should complete in 25 hours

If the temperature of milk is raised again 10^o C, the rate should once again should become double, that is rate is increased 3 times when compared to rate at 6^o C and therfore reaction should complete in 6 hours

therefore at 17 hours reacton should comlete in 23 hors( slghtly less than at 25 degree)
