Question

If the rate of reaction increases to two times with every ${10}^o$ rise in temperature, then if we raise the temperature by ${40}^o$, the new rate of the reaction will be:

• A. $4$ times
• B. $8$ times
• C. $16$ times
• D. $32$ times

Answer 1

The correct option is C $16$ times

Rate of reaction increases two times with every ${10}^{o}C$ rise in temperature.

Then, the Rate of reaction changes by $2^n$ times, where n is number of times the ${10}^o$ raises until it reaches the final temp.

If we raise the temperature by ${40}^o$, the new rate becomes $2^4=16$ times.
