The rate of a reaction is doubled for every \[\text{1}{{\text{0}}^{\text{o}}}\] rise in temperature. The increase in reaction rate as a result of temperature rise from \[\text{1}{{\text{0}}^{\text{o}}}\] to \[\text{10}{{\text{0}}^{\text{o}}}\] is:

A)  112          

B)  512

C)  400          

D)  614

Correct Answer: B

Solution :

 Key Idea: The rate of reaction increases by \[{{(2)}^{n}}\]for every \[{{10}^{o}}\] rise in temperature. \[\therefore \]rate of reaction increase 512 times.
