The rate of a chemical reaction is almost doubled for every 10°C rise in temperature. The rate will increase ______________ times, if the temperature rises from 10 to 100°C?
Correct answer: B
Explanation
The temperature rises by 90°C (100-10). Since the rate doubles for every 10°C rise, there are 9 intervals of 10°C. The increase is $2^9 = 512$ times.
