help with integrated rate laws
« on: March 27, 2012, 04:39:37 PM »
The rate law for second order is shown below..
but I'm not sure how to calculate the 0 attached to the concentration A
at the end of the equation. do i treat it as an exponent and make it 1. or not? I'm confused on the calculations! please help.

[A] and [A]0 are two different terms - [A]0 is the concentration of component A at the beginning of the reaction and is a constant for any single reaction, and [A] with no subscript is the concentration after time t, a dependent variable depending on time.

If you graph 1/[A] against time, 1/[A]0 will be the y intercept.
