Question

The rate of reaction becomes 2 times for every $10^{o}C$ rise in temperature. How the rate of reaction will increases when temperature is increased from $30^{o}C$ to $80^{o}C$

• A. 16
• B. 32
• C. 64
• D. 128

Answer 1

Answer: (B)

32

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.
