  5. Question 5

    Chemical Kinetics. Asked once: 4 Apr 2024

    145
    Consider the following reaction, the rate expression of which is given below
    A+B→CA + B \rightarrow C
    rate =k[A]1/2[ B]1/2= k\lbrack A\rbrack^{1/2}\lbrack\text{ }B\rbrack^{1/2} The reaction is initiated by taking 1M1M concentration AA and BB each. If the rate constant (k)(k) is 4.6×10−2 s−14.6 \times10^{- 2}{\text{ }s}^{- 1}, then the time taken for AA to become 0.1M0.1M is _____ sec. (nearest integer)
