The temperature coefficient of a reaction is 2. When the temperature is increases from 30 ° C to 90 ° C , the rate of reaction is increased by

Options

  1. A150 times
  2. B410 times
  3. C72 times
  4. D64 times

Correct answer

D. 64 times

Step-by-step solution

Temperature coefficient 2 means rate of reaction doubles at every 10 ° C rise in temperature. Thus, k 90 ° C k 30 ° C = 2 6 = 64
