Question

The velocity of the chemical reaction doubles every $10^{o}C$ rise of temperature. If the temperature is raised by $50^{o}C$, the velocity of the reaction increases to about.

• A. 32 times
• B. 16 times
• C. 20 times
• D. 50 times

Answer 1

Answer: (A)

32 times

Answer 2

$\frac{K_{t} + 10}{K_{t}} = \frac{r_{t} + 10}{r_{t}} = 2$; For an increase of temperature to $50^{o}C$, i.e. 5 times, the rate increases by $2^{5}$times, i.e. 32 times.
