Question

The temperature coefficient of a reaction is 2. When the temperature is increased from $30^{\circ} C$ to $90^{\circ}C$, the rate of reaction is increased by

• A. 150 times
• B. 410 times
• C. 72 times
• D. 64 times

Answer 1

Answer: (D)

64 times

Answer 2

Increase in temperature = $2^{\frac{\Delta T}{10}}$ $= 2^{\frac{60}{10}}$ $= 2^{6}$ $= 64$
