    A catalyst lowers the activation enegy of a reaction from \[20kJ\text{ }mo{{l}^{-1}}\] to\[10kJ\text{ }mo{{l}^{-1}}\]. The temperature at which the uncatalyzed reaction will have the same rate as that of the catalyzed at \[27{}^\circ C\] is

    A) \[-123{}^\circ C\]        

    B) \[327{}^\circ C\]

    C) \[32.7{}^\circ C\]                     

    D) \[+23{}^\circ C\]

    Correct Answer: B

    Solution :

    [b] \[\frac{E'a}{{{T}_{1}}}=\frac{E'a}{{{T}_{2}}}=\frac{10}{300}=\frac{20}{{{T}_{2}}}\] \[\therefore \text{ }{{\text{T}}_{2}}=600K=327{}^\circ C\]
