## First order plot

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### First order plot

What does the straight line plot of the natural log of reactants vs. time say about the reaction?

A straight line plot of the natural log of reactants vs. time would imply that the reaction is at first order.

the straight-line plot essentially means that as the reaction proceeds, the natural log of the reactant declines at the rate constant of k and is in first-order, and doesn't accelerate or decline across a particular time span.

### Re: First order plot

it is used to derive k as it is the negative slope of the equation.
