Q. If a graph is plotted between $\log (a-x)$ and $t$, the slope of the straight line is equal to $-0.03$. The specific reaction rate will be

Chemical Kinetics

Solution:

Graph of $\log (a-x)$ vs $t$ is a straight line, which shows first order reaction

$k=(-2.303) \times(-0.03)$
$=0.069=6.9 \times 10^{-2}$
