Question

Temperature coefficient of a reaction is 2. When temperature is increased from 30$^\circ$C to 100$^\circ$C, rate of the reaction increases by

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

Answer 1

Answer: (C)

128 times

Answer 2

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