    The velocity of the chemical reaction doubles every \[10{}^\circ \,C\] rise of temperature. If the temperature is raised by \[50{}^\circ \,C\], the velocity of the reaction increases to about

    A) 32 times           

    B) 16 times        

    C) 20 times           

    D) 50 times        

    Correct Answer: A

    Solution :

    \[\frac{{{K}_{t}}+10}{{{K}_{t}}}\,\,=\,\,\frac{{{r}_{t}}+10}{{{r}_{t}}}\,\,=\,\,2\]; for an increase of temperature to \[50{}^\circ \,C\], i.e. 5 times, the rate increases by \[{{2}^{5}}\] times, i.e. 32 times.
