    In a reaction, \[2A\to \] products, the concentration of A decreases from 0.50 M to 0.38 M in 10 min. What is the rate of reaction (in\[M\text{ }{{s}^{-1}}\]) during this interval?

    A) 0.012               

    B) 0.024

    C) \[2\times {{10}^{-3}}\]            

    D) \[2\times {{10}^{-4}}\]

    Correct Answer: D

    Solution :

    [d] Rate of reaction \[=\frac{d[A]}{dt}\] Given, \[{{[A]}_{initial}}=0.50\,M\] \[{{[A]}_{final}}=0.38\,M\] \[dt=10\text{ }min=600\text{ }sec\] \[d\left[ A \right]=0.12\] \[Rate=\frac{0.12}{600}=2\times {{10}^{-4}}M\,{{s}^{-1}}\]
