    The temperature coefficient for reaction in which food deteriorates is 2. Then food deteriorates ? times as rapidly at \[25{}^\circ \,C\] as it does at\[5{}^\circ \,C\].

    A) two                              

    B) four

    C) six                               

    D) twenty

    Correct Answer: B

    Solution :

    \[\frac{{{K}_{t}}+10}{{{K}_{t}}}\,\,=\,\,\frac{{{r}_{t}}+10}{{{r}_{t}}}\,\,=\,\,2\] For an increase of temperature to \[20{}^\circ C\] i.e., 2 times, the rate increase by \[{{2}^{2}}\] times, i.e. 4 times.
