    If the half-life of an isotope X is 10 years, its decay constant is :

    A)  \[6.932y{{r}^{-1}}\]       

    B)         \[0.6932\text{ }y{{r}^{-1}}\]      

    C)         \[0.06932\text{ }y{{r}^{-1}}\]                    

    D)         \[0.006932\text{ }y{{r}^{-1}}\]

    Correct Answer: C

    Solution :

    We know that, \[\lambda =\frac{0.693}{{{t}_{1/2}}}\] \[=\frac{0.693}{{{t}_{1/2}}}\] \[=0.0693y{{r}^{-1}}\]
