Answer:

Suppose we have to plot a graph of the reactant concentration versus time graph then we will use some simple formula already learnt in chemical kinetics that is

Rate = Reaction constant * [ Concentration ] ^ Order

Now,

If we put 0 as the order then the value of concentration will become 1 due to concentration^0 = 1

So, the rate will Become the constant value of reaction constant and hence the graph will be a straight line parallel to the x-axis

Suppose if we put order as 1

Then, the rate = constant * Concentration

which again is a constant value however changes proportionally to the value of concentration of the reactant and hence, this line when drawn on the graph will be x=y passing through the origin at time t=0

And thus having a slope of -1.

Hope this helps you and you've understood the concept
