Determining order

Postby Dang Lam » Wed Feb 28, 2018 9:53 pm

For example 15.2 in the textbook, how did they determine the order of H3O+? Like I am confused with the method they were using with fc and ln. Can someone please explain? Thank you

They determined the concentration of H3O+ from steps 2 and 4. In these steps, both BrO3- and Br- are staying the same initial concentration. However, only H3O+ is changing. Therefore, by using these two steps, find the exponent of H3O+.
And fc and ln is just another way of finding the exponent. They are breaking it down to the simplest form. It's just another way of writing an equation, just with different letters.
