    The rate of a reaction is doubled for every\[10{}^\circ \]rise in temperature. The increase in reaction rate as a result of temperature rise from\[10{}^\circ \]to\[100{}^\circ \]is:

    A)  112                                       

    B)  512

    C)  400                       

    D)         614

    E)  100

    Correct Answer: B

    Solution :

    \[10\xrightarrow[{}]{2}20\xrightarrow[{}]{4}30\xrightarrow[{}]{8}40\xrightarrow[{}]{16}\] \[50\xrightarrow[{}]{22}60\xrightarrow[{}]{64}70\xrightarrow[{}]{128}80\xrightarrow[{}]{256}\] \[90\xrightarrow[{}]{512}100\] So, increase in the reaction rate is 512.
