Slope From

Postby Sarah Sharma 2J » Tue Mar 06, 2018 10:18 am

Can someone please explain why it is important for us to know the slope-intercept form for some of the equations?

As far as I know it just helps with identifying what the rate constant is.

For zero order,
y-intercept is initial concentration and slope is -k (rate constant)

For first order,
y-intercept is the natural logarithm of initial concentration and slope is -k

For second order,
y-intercept is the inverse of initial concentration and slope is k

The slope-intercept form just help you remember these equations.

The slope form is important in identifying the rate constant and also the order when given concentrations.

It can help you to identify the rate constant.

By plotting the experimental data vs time, you would be able to identify the order of the reaction depending on whether [A] vs time, ln[A] vs time , or 1/[A] vs time gave you a straight line plot, where A is the reactant. Also, the slope would tell you what k is.
