(C) The integrated rate equation for a first order reaction is given by:$k = \frac{2.303}{t} \log \frac{a}{(a-x)}$Rearranging this equation:$\frac{kt}{2.303} = \log a - \log (a-x)$$\log (a-x) = -\frac{k}{2.303} t + \log a$This equation is in the form of a straight line $y = mx + c$,where $y = \log (a-x)$,$x = t$,slope $m = -\frac{k}{2.303}$,and intercept $c = \log a$.Therefore,a plot of $\log (a-x)$ versus $t$ yields a straight line with a negative slope.

Which one of the following plots is correct for a first order reaction?
