  • question_answer
    The number of electrons delivered at the cathode during electrolysis by a current of 1 ampere in 60 seconds is (charge on electron \[=1.60\times {{10}^{-19}}C)\]

    A)  \[6\times {{10}^{23}}\]                      

    B)  \[6\times {{10}^{20}}\]

    C)  \[3.75\times {{10}^{20}}\]                  

    D)  \[7.48\times {{10}^{23}}\]

    Correct Answer: C

    Solution :

    \[Q=I\times t\] \[=1\text{ }A\times 60s\] = 60 C ∴ No. of electrons \[\frac{60}{1.602\times {{1}^{-1}}}\] \[=3.75\times {{10}^{20}}\]
