Rate Law
« on: April 27, 2008, 01:11:34 PM »
I had to derive a formula for a reaction order of -1 in A.  The reaction is A arrow B.
Then had to sketch a graph.

I already did the math and all but wanted to know what the formula is.
Also the graph I have is a straigt line going up becuase of positive k value.  Just want to know if I am on the right track.

That's not right.  What is the differential rate law that you're starting with?

Basically I have to derive a formulat that indicates the linear dependence of concentration as a function of time for the reaction
A → B that has a reaction order of -1 in A.

I used-
Rate = k[A]-1 (-1 is exponent)

Rate = -d[A]/dt

That equation is correct, but when I solve that differential equation, I don't get a linear relation between [A] and t.
