Question

The temperature coefficient of a reaction is 2. When the temperature is increased from ${30}^{o}Cto{100}^{o}C$, rate of the reaction increases by:

• A. 128 times
• B. 100 times
• C. 500 times
• D. 250 times

Answer 1

Answer: (A)

128 times

The temperature is increased from ${30}^{o}Cto{100}^{o}C.$
$n=\frac{100-30}{10}=7$
The number of times the rate increases $=2^n=2^7=128$
