Question

When the temperature is increased by 10 K, the rate of reaction becomes double. How many times the rate of reaction will be if the temperature is increased from 303 K to 353 K?

• A. 4
• B. 8
• C. 16
• D. 32

Answer 1

Answer: (D)

32

Explanation:

By increasing $10K$ temperature the rate of reaction becomes double.

According to the given condition, When temperature is increased from 303 K to 353 K, the rate increases in steps of ${10}^0$ and has been made $5$ times i.e. from $303K\to 313K$, from $313K\to 323K$, from $323K\to 333K$,$333K\to 343K$, and finally from $343K\to 353K$,Hence, the rate of reaction should increase $2^5$times, i.e., 32 times.

Option D is correct
