Hey there, I'm trying to find out how to plot the graphs to determine if a reaction is a 0,1,2 order but having confusion between different equations.

I believed the answer was
0: [A] vs t
1: ln[A] vs t
2: 1/[A] vs t

But reading my lecturers notes he has it this way which gives different readings.

1:ln([A]0/[A]) vs t
2:1/[A] - 1/[A]0 vs t.

The example questions I have give different readings to both methods. So I'm lost to the correct technique.

Thanks.

All you want to do is check for linearity, right?

The two forms only differ by  a constant, so you'll get a different intercept.

Ok cheers mate, so both will give the correct answer?
