    For a first order reaction, a plot of log \[\left( a-x \right)\] against time is a straight line with a negative slope equal to

    A) \[\frac{-k}{2.303}\]

    B) \[-2.303k\]

    C) \[\frac{2.303}{k}\]                    

    D) \[-\frac{{{E}_{a}}}{2.303R}\]

    Correct Answer: A

    Solution :

    [a] \[t=\frac{2.303}{k}\log \frac{a}{a-x}\] or \[t=\frac{2.303}{k}\log \,a-\frac{2.303}{k}\log (a-x)\] \[\log (a-x)=\frac{-k}{2.303}t+\log a\]
