A) 256 times
B) 512 times
C) 64 times
D) 128 times
Correct Answer: B
Solution :
[b] For 10° rise in temperature, n = 1 so rate \[={{2}^{n}}={{2}^{1}}=2\] When temperatilse is increased from 10°C to 100°C, change in temperature = 100 - 10 = 90° C, i.e., n = 9 So, rate = 29 = 512 times |
Alternate method With every 10° rise in temperature, rate becomes double, so |
\[\frac{r'}{r}={{2}^{\left( \frac{100-10}{10} \right)}}={{2}^{9}}=512\,\text{times}\text{.}\] |
