Solution

Graphical representation of zero-order reactions: The rate law is given as 

which is a straight line given by y = mx + c.

A plot of `["A"]_"t"` versus t is a straight line.

[A]t vs t for zero-order reaction

The slope of the straight line is -k and its intercept on the y-axis is `["A"]_0`.
