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

Text Solution

Verified by Experts

The correct Answer is:
64
Temperature coefficient is 2 that means rate of reaction doubles at every 10°C rise in temperature.
Thus, `(k_(90^(@)C))/(k_(30^(@)C))=2^(6)=64`
