Question

Temperature coefficient of a reaction is '$2$'. When temperature is increased from $30$ to $90$, the rate of reaction is increased by :

• A. $60$ times
• B. $64$ times
• C. $150$ times
• D. $400$ times

Answer 1

Answer: (B)

$64$ times

Temperature coefficient gives the ratio of the rate of a reaction when the temperature increases by $10K$

When the temperature increases from $30$ to $90$ the reaction rate is increased $2^6$ times. i.e. $64$ times since there is 6 times $10K$ rise in temperature.
