zero order reaction

Why is it a zero order reaction with slope -k if the straight line fits to the data?

Re: zero order reaction

The slope is -k because the integrated rate law for zero order is
-kt + [A]o = [A]

similar to the straight line y= mx + b

[A] = -kt + [A]o

Re: zero order reaction

The integrated rate for a first order reaction is A= -kt + Ao which is in the form of a linear equation where -k is the slope.

Re: zero order reaction

A zero order equation integrated gives a first order equation, which when graphed, gives a straight line, as opposed to a second order equation, like something with x^2, that gives a parabola.
