Question

The rate of a reaction is doubled for every $10^{o}$ rise in temperature. The increase in reaction rate as a result of temperature rise from $10^{o}$ to $100^{o}$ is.

• A. 112
• B. 512
• C. 400
• D. 614

Answer 1

Answer: (B)

512

Answer 2

$\frac{k_{t} + 10}{K_{t}} = \frac{r_{t} + 10}{r_{t}} = 2$

For an increase of temperature to $90^{o}C$ i.e. 9 times, the rate increases by $2^{9}$ times i.e. 512.
