JEE Main & Advanced Chemistry Chemical Kinetics / रासायनिक बलगतिकी Question Bank Rate law and Rate Constant

  • question_answer
    For a first order reaction, rate constant is \[0.6932\,h{{r}^{-1}}\], then half-life for the reaction is               [Bihar MEE 1997]

    A)                 \[0.01\,hr\]        

    B)                 \[1\,hr\]

    C)                 \[2\,hr\]

    D)                 \[10\,hr\]

    E)                 \[0.1\,hr\]

    Correct Answer: B

    Solution :

                    \[{{t}_{1/2}}=\frac{0.693}{k}=\frac{0.693}{0.6932\,\,h{{r}^{-1}}}=1\,\,hr\].
